3d 'bouncy cubes' demo.
This program demonstrates how to use the 3d matrix functions.
It isn't a very elegant or efficient piece of code, but it
does show the stuff in action. It is left to the reader as
an exercise to design a proper model structure and rendering
pipeline: after all, the best way to do that sort of stuff
varies hugely from one game to another.
The example first shows a screen resolution selection dialog.
Then, a number of bouncing 3d cubes are animated. Pressing
a key modifies the rendering of the cubes, which can be
wireframe, the more complex transparent perspective correct
texture mapped version, and many other.
