Re: New function ggiFlushRegion()

Is this a good idea? Thinking specifically of my game .. I could, perhaps,
improve performance on the X target by updating only the necessary regions ...
this would probably amount to (say) 2 or 3 ggiFlushRegion calls in a single
frame (which may or may not improve performance, depending on the overhead.
Right now it's just a single ggiFlush per frame.) The problem here would be
that if the same binary was run in console mode, or on the svgalib target, the
same code would produce 3 entire screen flushes, clearly *not* optimal, if, as
you say, it would be identical to ggiFlush. Or am I confused?

I'm not complaining or anything. I think this is a very useful new function,
and a good idea.
