color, text, and bitmaps

[Ranson <ranson@LANNION.cnet.fr>]

For color, you have to use a pixmap (similar to a bitmap, but with several bits
per pixel). Bitmaps can only store black and white.

I'm not sure what you want for text. You can draw text to your bitmap using
DrawString or DrawText. If you want to overlay text on your drawing and be able
to change it afterwards, you may want to use several bitmaps and combine their
contents on screen with transfer modes.
