*
* The problem, as of 2017-05-30:
* When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel
* order and chooses the first __DRIconfig with the expected channel
* sizes. Specifically, GLX compares the GLXFBConfig's and __DRIconfig's
* __DRI_ATTRIB_{CHANNEL}_SIZE but ignores __DRI_ATTRIB_{CHANNEL}_MASK.
*
* EGL does not suffer from this problem. It correctly compares the
* channel masks when matching EGLConfig to __DRIconfig.
