Well, your patch does seem to eliminate the problem, but there is a subtle
difference between how things works now and before, which I think may be
questionable.
The spec of EGL_KHR_create_context says:
requesting a forward-compatible context for OpenGL versions less
than 3.0 will generate an error
The code now takes "OpenGL version" above as version requested with EGL (1.0 by
default). However, the OpenGL version actually provided can be up to 3.0. In
such case, your patch will fail to create forward-compatible context, giving
the "appropriate" error, while mesa before 86ccb2a1 will succeed. Though both
behaviors pass piglit.
Any ideas?</pre>
