egl: Fixes transparency with EGL and X11.
This commit does this by allowing both RGB and RGBA visuals to match with EGL configs. We also expose the `EGL_MESA_config_select_group` egl extension, which is similar to GLX's visual select group extension, to allow the RGBA visuals to get less priority. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=67676 Fixes: 049f343e8ac "egl: Allow 24-bit visuals for 32-bit RGBA8888 configs" Cc: [email protected] Reviewed-by: Adam Jackson <[email protected]> Signed-off-by: Hal Gentz <[email protected]>
