Subject: glx: Add an error message when a direct renderer's createScreen() routine fails
X-Git-Tag: android-x86-4.4-r3~4814
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=83821ece79011d21303058e30694dd3796d072f2;p=android-x86%2Fexternal-mesa.git

glx: Add an error message when a direct renderer's createScreen() routine fails
because no matching fbConfigs or visuals could be found.

Nearly all the error cases in *createScreen() issue an error message to diagnose
the failure to initialize before branching to handle_error.  The few remaining
error cases which don't should probably do the same.

(At the moment, it seems this can be triggered in drisw with an X server which
reports definite values for MAX_PBUFFFER_(WIDTH|HEIGHT|SIZE), because those
attributes are checked for an exact match against 0.)
