Would it be better to still default to GLX and have a flag to use EGL (and 
switch within a few releases), or to go with EGL and have a flag to fallback to 
GLX?

Currently (on this PR) it defaults to EGL first, and if it fails, try GLX (I 
don't know a scenario where EGL won't work, on Xorg o XWayland).
