Title: renderer: allow some lateness within vblank interval

this prevents renderer from skipping frames which are not really late. vblank might have already accured when entering PrepareNextFrame. Im this case renderer can catch up.

This is follow up from #4856 by @ossman. Fixes fps dropping to 12 fps with RenderCapture engaged.
