Plumb overlay processing into DirectRenderer.

This change tests for overlays inside DirectRenderer::DrawFrame and if
new overlay passes were produced, it skips rendering them and forwards the
information to FinishDrawingFrame to allow subclasses like GLRenderer and
SoftwareRenderer to schedule overlays in a manner specific to their
implementation.

GLRenderer schedules overlays via ContextSupport.

Adds more tests to ensure overlay quads are not drawn and if no overlays
are present, no quads are skipped.
