I was just working on the same problem when I saw
your post. There is a way to do this without having to hack
code. As I myself learned from this list, the ticks
are markers. The trick is to set the markeredgewidth
of the ticks. For example:
plot1 = subplot(111,axisbg='w')
set(plot1.get_xticklines() + plot1.get_yticklines() , mew=3.0)
This should do the trick.
