The 2D engine must take care about synchronization itself.
AFAICT, your change to SCREEN_TO_SCREEN_BLIT() shouldn't have been 
necessary, as the app_server must sync the screen before accessing bits 
that might have been clobbered by the acceleration engine - if it 
doesn't do this, either the app_server or your engine synchronization 
code is broken.
