[Mesa3d-dev] [PATCH] dri2: print fallback to swrast with LIBGL_DEBUG

[Xavier C. <cha...@gm...>]

This just changes the error message printed with LIBGL_DEBUG when loading
dri2 driver fails. It makes it more informative, more consistent with second
fallback swrast->indirect , and possibly more consistent with old dri1
behavior.

OLD:
libGL error: dlopen foo/nouveau_dri.so failed (foo/nouveau_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing
libGL error: dlopen foo/swrast_dri.so failed (foo/swrast_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: swrast_dri.so
libGL error: reverting to indirect rendering

NEW:
libGL error: dlopen foo/nouveau_dri.so failed (foo/nouveau_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: nouveau_dri.so
libGL error: reverting to software direct rendering
libGL error: dlopen foo/swrast_dri.so failed (foo/swrast_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: swrast_dri.so
libGL error: reverting to indirect rendering
