Acquire/Release has nothing to do with whether you use LibGGI
primitives or not. If acquireing the DB is necessary you have to
do it regardless, and you have to release it before you call
ggiFlush().

The normal application cycle would look like this:

while (!quit) {
	do_stuff()
	ggiResourceAcquire();
	draw_to_db();
	ggiResourceRelease();
	do_more_stuff();
	ggiFlush();
}
