gtk3: flicker-free opengl transitions
leave the GtkGLArea opengl context alone except for the final render into
it,
create a new context for the slide transitions to play with
set up a pair of framebuffers, a scratch one to let the transitions render
into, the other to take a snapshot when the transition is finished with it
and
then tell GtkGLArea we're ready to render it and when the callback comes
around
copy the snapshot into it.
