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

[Jon TURNEY]

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.)
