gstlglimagesink EGL_BAD_DISPLAY

[Marc Leeman]

Some bit if success,

after backporting mesa 19.1.0 to debian 10 and using the nouveau drivers,
mutter starts again

My patched GStreamer (ugly as hell) is able to start

videotestsrc ! glimagesink

the plugins-base master fails, if I were to guess, it has to do with the
new colour spaces that are exposed:

eglChooseConfig returns [R, G, B, A] [10, 10, 10, 0].

I'll weed out the relevant parts.
