Thanks for your reply... I was just wondering what the difference between
building a pixmap and building an RGB buffer internally is... because the
way I do it now, I build the pixmap and then display it all at once on the
drawing area. Thanks,
rok

If you use GDK RGB buffers, then you can internally
blit your 1024x1024 buffer in local memory then send
it all at once (or just a rectangular area) to the
GtkDrawingArea's GdkWindow.
