egl: don't bind the wayland display if the extension is not available (1.22 KB, patch)

Description Giovanni Campagna 2013-07-23 15:12:03 UTC 
When running in a purely swrast environment (such as with
LIBGL_ALWAYS_SOFTWARE), the extension is not exposed by mesa,
but wayland is still possible with wl_shm.

Marking for review for 3.10, because this blocks running mutter-wayland on any form of SW rendering.

I've pushed the patch to the master and 1.16 branches.

I think we also need some way to report that the extension isn't available, perhaps via a feature flag. We should also make cogl_texture_2d_new_from_wayland_buffer fail with an error instead of crashing in that case. But those are both separate issues.
