Allow for more flexible vsync-offsets

The issue with just one single sf early offset is that this may be
too early in case of steady rendering, i.e. when a
Wide-Color-Gamut window is on screen. Instead, we allow for
separate offsets in case we are in GL comp but the transaction
wasn't marked as early, and when the transaction is marked as
early.

In addition to that, we also allow the app-vsync to be adjusted
in these scenarios.
