I want to set a region to the shape of a picture, so that when I use
copyBits to blit it back from an offscreen bitmap it can mask the picture,
thus protecting others already on screen. I have seen Pascal code from
other programs like this....

aRgn := neRgn;
openRgn;
drawPicture(aPic,aPic^^.picFrame);
closeRgn(aRgn);

....Except when I do it all I get back is an empty region. So how do I do
what I want to do?
