Restore glimagesink instead of ximagesink
Restore glimagesink instead of ximagesink

Partially revert previous commit. It's not an issue with glimagesink
Xoverlay interface. It's always the same intel bug with direct
rendering redirection (the one that affects each opengl application
with compositing managers). It works fine with DRI2 and UXA
acceleration. Still leaving effects disabled because I'm testing intel
hardware that doesn't support FBOs.
