Page 13 of the tracemonkey file is now "blocky", this wasn't before.

This seems like a regression but it isn't really, it's a manifestation of the
problem with AWT Paint. The previous code worked because of a fluke which is
not present in my implementation. The same applies to the tiling_pattern file.
I'm going to conduct some experiments with AWT Paint and report on the results
soon so that we can figure out how to solve the problem. Rending the patterns
using the pattern coordinate system is *not* a goos solution, for the files we
have it happens to use a scaling > 1 and so the patterns that now look
pixelated appeared crisp, however there is no reason why a pattern cannot using
a scaling < 1 which would give results even more pixellated than the current
solution!
