grafx - Extensible Java Graphics Package Code

Adding beginnings of class TiledDepthGraphics. This is only for test code.

Adding file JDK-1_0_2-api.zip.

Voila! And the last remaning java.* import statement has been removed.

Fixing some Javadoc issues.

Changing DEFAULT_MAX_FPS once again, this time to 250. I think that this is
the correct value unless/until we look at the architectural possibilities for
how else to do this (want to keep popping events off the user events list, and
want to keep SimpleGameLogic running fluidly).

Here is a first pass at changing RasterDepthPixBuff from an interface to an
abstract class. This is so that default values could be chosen in most cases,
without the need to override almost ten methods.

Adding a few lightweight comments.

I think this is the correct way to handle clip and clear().

Going the other way in changing DEFAULT_MAX_FPS to 500. This makes the game
more responsive.

Changing DEFAULT_MAX_FPS from 200 to 125.
