grafx - Extensible Java Graphics Package Code

TODO, need to implement intersection().

I think I'm going to avoid this complex boolean logic. My brain just isn't
able to really handle it. I prefer the simpler approach.

For some reason this finite discrete boolean logic always baffles me.

Okay, it's good that we're finally finding these issues. We have some work to
do, after some rest.

I think this is the update I needed for ClipRectangle. It's in one of three
states: isArea(), isDegenerate(), or isInverted().

Adding TestClip which exposes a bug with setClip().

Adding a Javadoc TODO.

Am stuck on clipping in TiledDepthGraphics. Had to add the getPointAlias()
method to DepthGraphics interface, unfortunately.

Making some progress on TiledDepthGraphics.

Making a little bit more progress on TiledDepthGraphics.
