Thanks for the hints, guys. Those Windows control panels sure are cluttered and poorly organized! Now that I've enabled ClearType I've been able to reproduce the problem. It seems to be a bug in Pango itself; the metrics it is reporting seem too small by a pixel or so in some cases, and creating an offscreen context with additional padding doesn't help.
Since my Uniscribe binding is coming along pretty well, I'd rather not spend more time debugging Pango. It has another show-stopper problem on 64-bit Windows as well, so we have to stop using it eventually anyway. I'll just focus on Uniscribe -- it should be ready in a few days. In the meantime, you can disable ClearType, or use an older Factor release.
