Michael Natterer ae72971866 app: pass the orig_tiles and their offset to GimpTransformTool::transform()
instead of keeping them around as members. This is another artifact
from ancient times. Also get rid of some more legacy junk
code. Disable more code in GimpTransformToolUndo but keep it around
even though it does nothing at the moment.
