Changes from alpha 0.3:
- Now uses a higher resolution game window (640x512) and more sprite images.
- Sprites are now fully V-reversible as well as H-reversible.
- 90 degree rotation is possible for the pacman sprite (now also stored in rotated form).
- Some Amiga-style "boing ball" and "checkmark" sprites (and the jAMAL logo) were added to the examples.
