[Mesa-dev] [PATCH v2] egl: check if colorspace/surface type is supported

[Juan A. Suarez Romero]

According to EGL 1.4 spec, section 3.5.1 ("Creating On-Screen Rendering
Surfaces"), if config does not support the colorspace or alpha format
attributes specified in attrib_list (as defined for
eglCreateWindowSurface), an EGL_BAD_MATCH error is generated.

This fixes dEQP-EGL.functional.wide_color.*_888_colorspace_srgb (still
not merged,
https://android-review.googlesource.com/c/platform/external/deqp/+/667322),
which is crashing when trying to create a windows surface with RGB888
configuration and sRGB colorspace.

v2: Handle the fix in other backends (Tapani)
