Comment (by Ionic):

 I think I'll probably make `cocoa` and `x11` conflicting as well. Linking
 both runtimes at the same time (like we did it before) probably calls for

 Try `gst-launch-1.0 -v gltestsrc ! glimagesink` to see the effect with a
 `+cocoa+x11`-enabled `gstreamer1-gst-plugins-base` package. It's being
 rendered through X11 (and not Cocoa), but the output is... a garbled,
 flickering mess of random(?) pixmaps. Not the SMPTE test pattern one would

 gstreamer includes the system GL headers in a hardcoded fashion `#ifdef
 __APPLE__`, which has been causing the compile failures even in the `+x11`

 Ryan, do you have any idea how wine uses gstreamer? Probably just for
 conversion, but not for actual rendering, right? I guess it should be
 pretty agnostic when it comes to the gstreamer GL backend?

 If I make `x11` and `cocoa` conflicting, we'll only be able to enable one
 backend at a time. I'll likely go for `+x11` on platforms not supporting
 `+cocoa`, otherwise `+cocoa`.
