- CSHOW is great at dithering pictures into resolutions you do not have.
- Simple math shows you that getting true 640x480x256 cannot be done with only
- 256k of frame buffer. Each pixel is one byte, so 640x480 > 256k.

- Moral of the story: Use a picture viewer that doesn't unknowingly trick you
- into thinking you have resolutions you don't.
