grafx - Extensible Java Graphics Package Code

This is the newly autogenerated Blocks class, mirrors paired.

In net.blockout.production.Blocks, the order of blocks listed will now have
them grouped by mirror pairs, in the cases where there are mirror pairs.

I think this is all the ideas I had. They came to me all at once. I may have
forgotten something.

Reverting back to grafx-2.2 code. I had to make some "jumps" because I wanted
diffs in the right direction, didn't know how to immediately do it without lots
of error-prone techniques.

Temporarily committing grafx-2.0 files, to get a forward diff from 2.0 to 2.1.
Again, I'm struggling with a very simple task which is taking a patch file and
reversing it. If I don't read a forward diff I may make mistakes in the
revision history documentation, the constant flipping in boolean logic makes my
brain hurt, I wasn't designed to do things that way. I'm not a computer.

This is the source ball (not including demo code) from grafx-2.1 release.
I'm trying to find a forward patch from 2.1 to 2.2, I don't want to compare
two directories. I want to do it here, by reversing a patch file that was
generated, to give a new patch file. After searching on the internet I found
no obvious links that demonstrate this, and from first glances neither 'diff'
nor 'patch' seem to be able to generate this for me. So I'm committing the
old code and will take the forward diff which will give 2.1->2.2 changes. It
less error prone to read.

Updating VERSION on 2D graphics library from 2.1 to 2.2. Making a mini
release, probably.

Moving over the most recent changes/improvements from 'blockout' branch to
'grafx' branch, related only to 2D rendering lib and demo support code.

Removing unused function bounded(), which was at one point added to try to
solve getClip(), and making unused method debugInclusiveBoundsPixelClip()
private so that it would not clutter up Javadoc.

Adding AliasPerformance.
