These are temporary, actually, but they'll make follow-on work easier to
implement in a step-by-step manner. Eventually the Map and RowStrideBytes
fields will go into a new swrast_renderbuffer type, but adding that type
now would involve touching a _lot_ of code that'll eventually be removed.
The fields marked as obsolete will go away completely at some point.
