[cairo] *gl-surface-source: CRASH! Re: make check failed while all tests passed

[darxus at chaosreigns.com]

Changing all the "return NULL"s to "return CAIRO_TEST_UNTESTED" didn't
help.

Adding "return NULL" right before "return surface", it says it's untested
instead of crashed.

That "return surface" looks really weird to me, but lots of the tests do
it.  How is this supposed to work?

    surface = cairo_gl_surface_create (device,
                                       CAIRO_CONTENT_COLOR_ALPHA,
                                       size, size);

    return surface;

None of that crashes when I run it on my regular X display instead of Xvfb:
