+ * path segments and at the intersection of the endpoints of a subpath. The
+ * BasicStroke defines three decorations: JOIN_BEVEL, JOIN_MITER, and
+ * JOIN_ROUND.</li>
+ * <li>miter limit - the limit to trim a line join that has a JOIN_MITER

+/**
+ * CommonGraphics2D class is a super class for all system-dependent
+ * implementations. It implements major part of Graphics and Graphics2D
+ * abstract methods.
+ * <h2>CommonGraphics2D Class Internals</h2>
+ * <h3>Line and Shape Rasterizers</h3>
+ * <p>
+ * The CommonGraphics2D class splits all shapes into a set of rectangles
+ * to unify the drawing process for different operating systems and architectures.
+ * For this purpose Java 2D* uses the JavaShapeRasterizer and the JavaLineRasterizer
+ * classes from the org.apache.harmony.awt.gl.render package. The JavaShapeRasterizer
+ * class splits an object implementing a Shape interface into a set of rectangles and
+ * produces a MultiRectArea object. The JavaLineRasterizer class makes line drawing
+ * more accurate and processes lines with strokes, which are instances of the BasicStroke
+ * class.
+ * </p>
+ * <p>
+ * To port the shape drawing to another platform you just need to override
+ * rectangle-drawing methods. However, if your operating system has functions to draw
+ * particular shapes, you can optimize your subclass of the CommonGraphics2D class by
+ * using this functionality in overridden methods.
+ * </p>
+
+ * <h3>Blitters</h3>
+ * <p>
+ * Blitter classes draw images on the display or buffered images. All blitters inherit
+ * the org.apache.harmony.awt.gl.render.Blitter interface.
+ * </p>
+ * <p>Blitters are divided into:
+ * <ul>
+ * <li>Native blitters for simple types of images, which the underlying native library
+ * can draw.</li>
+ * <li>Java* blitters for those types of images, which the underlying native library
+ * cannot handle.</li>
+ * </ul></p>
+ * <p>
+ * DRL Java 2D* also uses blitters to fill the shapes and the user-defined subclasses
+ * of the java.awt.Paint class with paints, which the system does not support.
+ * </p>
+ *
+ *<h3>Text Renderers</h3>
+ *<p>
+ *Text renderers draw strings and glyph vectors. All text renderers are subclasses
+ *of the org.apache.harmony.awt.gl.TextRenderer class.
+ *</p>

+ * -# startPreview() is called, which is passed a preview_callback()
+ * function and a user parameter. The camera instance then periodically
+ * calls preview_callback() each time a new preview frame is available.
+ * The callback routine has two parameters: the first is a pointer to
+ * the IMemory containing the frame and the second a user parameter. If
+ * the preview_callback code needs to use this memory after returning,
+ * it must copy the data.
+ *
+ * Prior to taking a picture, CameraService calls autofocus() with
+ * autofocus_callback() and a user parameter. When auto focusing has
+ * completed, the camera instance calls autofocus_callback(), which informs
+ * the application whether focusing was successful. The camera instance
+ * only calls autofocus_callback() once and it is up to the application to
+ * call autoFocus() again if refocusing is desired.
+ *
+ * CameraService calls takePicture() to request the camera instance take a
+ * picture. This method has two callbacks: raw_callback() and jpeg_callback().
+ * When the raw image is available, raw_callback() is called with a pointer
+ * to the IMemory containing the raw image. When the jpeg image is available,
+ * jpeg_callback() is called with a pointer to the IMemory containing the
+ * jpeg image. As with preview_callback(), the memory must be copied if it's
+ * needed after returning.

+ *********************************************************************** */
+
+/**
+ * This chunk specifies how to split an image into segments for
+ * scaling.
+ *
+ * There are J horizontal and K vertical segments. These segments divide
+ * the image into J*K regions as follows (where J=4 and K=3):
+ *
+ * F0 S0 F1 S1
+ * +-----+----+------+-------+
+ * S2| 0 | 1 | 2 | 3 |
+ * +-----+----+------+-------+
+ * | | | | |
+ * | | | | |
+ * F2| 4 | 5 | 6 | 7 |
+ * | | | | |
+ * | | | | |
+ * +-----+----+------+-------+
+ * S3| 8 | 9 | 10 | 11 |
+ * +-----+----+------+-------+
+ *
+ * Each horizontal and vertical segment is considered to by either
+ * stretchable (marked by the Sx labels) or fixed (marked by the Fy
+ * labels), in the horizontal or vertical axis, respectively. In the
+ * above example, the first is horizontal segment (F0) is fixed, the
+ * next is stretchable and then they continue to alternate. Note that
+ * the segment list for each axis can begin or end with a stretchable
+ * or fixed segment.
+ *
+ * The relative sizes of the stretchy segments indicates the relative
+ * amount of stretchiness of the regions bordered by the segments. For
+ * example, regions 3, 7 and 11 above will take up more horizontal space
+ * than regions 1, 5 and 9 since the horizonal segment associated with
+ * the first set of regions is larger than the other set of regions. The
+ * ratios of the amount of horizontal (or vertical) space taken by any
+ * two stretchable slices is exactly the ratio of their corresponding
+ * segment lengths.
+ *
+ * xDivs and yDivs point to arrays of horizontal and vertical pixel
+ * indices. The first pair of Divs (in either array) indicate the
+ * starting and ending points of the first stretchable segment in that
+ * axis. The next pair specifies the next stretchable segment, etc. So
+ * in the above example xDiv[0] and xDiv[1] specify the horizontal
+ * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and
+ * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that
+ * the leftmost slices always start at x=0 and the rightmost slices
+ * always end at the end of the image. So, for example, the regions 0,
+ * 4 and 8 (which are fixed along the X axis) start at x value 0 and
+ * go to xDiv[0] amd slices 2, 6 and 10 start at xDiv[1] and end at
+ * xDiv[2].
+ *
+ * The array pointed to by the colors field lists contains hints for
+ * each of the regions. They are ordered according left-to-right and
+ * top-to-bottom as indicated above. For each segment that is a solid
+ * color the array entry will contain that color value; otherwise it
+ * will contain NO_COLOR. Segments that are completely transparent
+ * will always have the value TRANSPARENT_COLOR.
+ *
+ * The PNG chunk type is "npTc".

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,

+Android Utility Function Library
+
+If you need a feature that is native to Linux but not present on other
+platforms, construct a platform-dependent implementation that shares
+the Linux interface. That way the actual device runs as "light" as
+possible.
+
+If that isn't feasible, create a system-independent interface and hide
+the details.
+
+The ultimate goal is *not* to create a super-duper platform abstraction
+layer. The goal is to provide an optimized solution for Linux with
+reasonable implementations for other platforms.

+San Angeles Observation OpenGL ES version example\r
+Copyright 2004-2005 Jetro Lauha\r
+Web: http://iki.fi/jetro/\r
+See file license.txt for licensing information.\r
+------------------------------------------------------------------------\r
+\r
+This is an OpenGL ES port of the small self-running demonstration\r
+called "San Angeles Observation", which was first presented in the\r
+Assembly'2004 event. It won the first place in the 4 KB intro\r
+competition category.\r
+\r
+The demonstration features a sightseeing of a futuristic city\r
+having many different kind of buildings and items. Everything is\r
+flat shaded with three different lights.\r
+\r
+The original version was made for desktop with OpenGL. It was\r
+naturally heavily size optimized in order to fit it in the size\r
+limit. For this OpenGL ES version example much of the code is\r
+cleaned up and the sound is removed. Also detail level is lowered,\r
+although it still contains over 60000 faces.\r
+\r
+The Win32 (2000/XP) binary package of original version is\r
+available from this address: http://jet.ro/files/angeles.zip\r
+\r
+First version of this OpenGL ES port was submitted to the Khronos\r
+OpenGL ES Coding Challenge held in 2004-2005.\r
+\r
+As a code example, this source shows the following:\r
+ * How to create a minimal and portable ad hoc framework\r
+ for small testing/demonstration programs. This framework\r
+ compiles for both desktop and PocketPC Win32 environment,\r
+ and a separate source is included for Linux with X11.\r
+ * How to dynamically find and use the OpenGL ES DLL or\r
+ shared object, so that the library is not needed at\r
+ the compile/link stage.\r
+ * How to use the basic features of OpenGL ES 1.0/1.1\r
+ Common Lite, such as vertex arrays, color arrays and\r
+ lighting.\r
+ * How to create a self contained small demonstration\r
+ application with objects generated using procedural\r
+ algorithms.\r
+\r
+As the original version was optimized for size instead of\r
+performance, that holds true for this OpenGL ES version as\r
+well. Thus the performance could be significantly increased,\r
+for example by changing the code to use glDrawElements\r
+instead of glDrawArrays. The code uses only OpenGL ES 1.0\r
+Common Lite -level function calls without any extensions.\r
+\r
+The reference OpenGL ES implementations used for this application:\r
+ * Hybrid's OpenGL ES API Implementation (Gerbera) version 2.0.4\r
+ Prebuilt Win32 PC executable: SanOGLES-Gerbera.exe\r
+ * PowerVR MBX SDK, OpenGL ES Windows PC Emulation version 1.04.14.0170\r
+ Prebuilt Win32 PC executable: SanOGLES-PVRSDK.exe\r
+\r
+Note that DISABLE_IMPORTGL preprocessor macro can be used\r
+to specify not to use dynamic runtime binding of the library.\r
+You also need to define preprocessor macro PVRSDK to compile\r
+the source with PowerVR OpenGL ES SDK.\r
+\r
+The demo application is briefly tested with a few other OpenGL ES\r
+implementations as well (e.g. Vincent, GLESonGL on Linux, Dell\r
+Axim X50v). Most of these other implementations rendered the demo\r
+erroneously in some aspect. This may indicate that the demo source\r
+could still have some work to do with compatibility and correct\r
+API usage, although the non-conforming implementations are most\r
+probably unfinished as well.\r
+\r
+Thanks and Acknowledgements:\r
+\r
+* Toni Lönnberg (!Cube) created the music for original version, which\r
+ is not featured in this OpenGL ES port.\r
+* Sara Kapli (st Rana) for additional camera work.\r
+* Paul Bourke for information about the supershapes.\r

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+\f
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+\f
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+\f
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+\f
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+\f
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+\f
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+\f
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+\f
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.
