store your bitmap in an offscreen window and then use WinCopyRectangle()
to blit it to the screen. you can specify the type of copying method
in the call (such as winPaint, winInvert, winMask, winOverlay etc)
if you only want it running on os 3.5, then you can probably use
WinPaintBitmap() (double check the method name, no API here right now)
- which does the same thing.. but ONLY under os 3.5
cheers.
