No worries.

Thanks for the very quick fix! Asking you for that was much easier
than if I had tried to diagnose and fix this myself.

This fix is all pushed out now, (still need to finish up a radial
gradient test case before pushing out those performance improvements).

With this fix, we've now got 2 out of the 3 bad bugs fixed that were
originally known in 1.3.12, and that I said we wanted fixed before

The third bug is the locking problems as described here:

	text rendering lacking locking in multithreaded apps [PATCH]

I've decided that we want to do a little more cleanup than in the
patches currently there in bugzilla. And if we're having to touch this
glyph cache code to fix its locking, we might as well fix it to
address some performance limitations already documented in the

So Keith and I are planning to work on those things on Monday.

Meanwhile, one other nasty bug has also cropped up that's in 1.3.12,
and that's the spacing problem in cairo_show_text with cairo-win32. Is
