| * |
| * The problem, as of 2017-05-30: |
| * When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel |

| * __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. |
