Printing is broken for tranformed glyphs.  The problem lies with
damage checking in Printer.  Briefly, printer uses the Canvas damage
check, which in turn uses the Canvas transformation matrix.  But
Printer does not propagate transformation changes through to Canvas.
The upshot is that transformed glyphs use incorrect transformations
for damage checks when printing.

    Apply with ``patch -p -N < fix5'' at the top of the source tree.
