Relative to J1.
This time around, lots of goodies in the REPORT drawing code.
We're still not drawing the image for the subitems, but that's
the subject of a different patch.
ChangeLog:
-- Fix the subitem drawing code
-- A lot faster drawing in report mode
-- A great deal of cleanup, and simplifications.
