grafx - Extensible Java Graphics Package Code

Adding script compile-video-small.sh.

Adding LaunchLevelPlaybackVideoRecorderSmall, which inherits from
LaunchLevelPlaybackVideoRecorder, and only has a small section of code in a
'static' block.

Adding some really interesting games that were recorded in real time.

Changing some dimensions in SmallCanvasConstantOverrides; it looks much better
now.

In NextBlockDisplay, if the block image is too small for allocated canvas
space, chopping area from the top of image instead of from bottom. This fits
better with game layout, e.g. GameSidebar.

In GameSidebar making some slight adjustments to text layout. Explicitly
defining local parameter 'xOffset' which is now set to zero, which determines
the x starting position of text. Text which wasn't left justified with the
next block display didn't look very good. Changing the indentation level of
descriptive text (not title text) to three characters; it was at two
previously.

Adding class net.blockout.production.SmallCanvasConstantOverrides. Still need
to fine tune this.

Renaming performBlockoutConstantOverrides() to
performTetrisConstantOverrides() in class TetrisConstantOverrides.

GameSidebar now uses a smaller font if the canvas size is too small for the
larger font.

Adding a TODO.txt item, having to do with 640x360 resolution.
