Got images working in the display list based Java2D output.
Implemented turning off and restoring anti-aliasing in the display list output device.
Cleaned up Java2DFontResolver and implemented font scaling.

Also removed comments about anti-aliasing and fractional metrics as
these are now expected to be set on the Graphics2D object passed in.
Deleted dead code.

ContentStore (an ill fated cache attempt) and NoReplacedElementFactory.
