Does PolyDraw() set up a series of blitter requests and then
return immediately, or does it wait until the blitter has finished
before it returns (ie by using WaitBlit() or somthing)?
What I'm getting at is this: is it possible to write my own polydraw()
that runs faster by accessing the blitter directly myself?
I have a graphics program that feels the need for speed.
     question 2:
Does anyone know of a fast way to draw a filled circle (or circle-like
polygon...) into a bitmap? I need it to work for circles of arbitrary
size and position. In other words, I need to clip it onto the screen.
I would use BeginArea()... etc but I am having trouble figuring out how
to do the clipping. Could I use layers somehow?  Is there a big penalty
for this?
                                     thanks,
                                   steve
