[Mesa-dev] [PATCH 09/10] egl/x11: Match depth 30 RGB visuals to 32-bit RGBA EGLConfigs.

[Mario Kleiner]

Similar to the matching of 24 bit RGB visuals to 32-bit
RGBA EGLConfigs.

Fixes failure of piglit egl tests to select ARGB2101010
visuals via eglChooseConfig() with EGL_ALPHA_BITS 2 on
a depth 30 X-Screen.
