Remove support for 'auto'(-1) value of XV_SYNC_TO_VBLANK
We previously had a heurstic here where we would only sync to vblank
for windows that covered more than 25% of the screen. We don't need
this anymore since the new approach to sync, (WAIT_FOR_SCANLINE_WINDOW),
is not excessively costly for small windows.
