A few questions concerning DirectDraw:

I'm trying to make a tiling effect - use bitmaps of a certain size to fill up the whole screen. What is the best way to approach this?

1) Is it possible to display multiple bitmaps on one surface? If so, how?

2) Is it possible to make the top-left corner of a surface in full-screen mode be anything other than (0,0)?

Thanks for any suggestions.
