--- Comment #2 from Jason Ekstrand <jason at jlekstrand.net> ---
There appear to be two potential problems here.  One is that Weston tries to
use GL_EXT_abgr in ES even though it is not an ES extension.  The second is
that mesa advertises it and then falls over when you try to use it.  If we
weren't advertising it, Weston would fall back to other paths and be OK.  I see
two options:

 1) Actually support the extension even though it isn't technically an ES
 2) Stop advertising it.

I'm going to hazard a guess and say that mesa is probably the only ES driver to
support GL_EXT_abgr.
