[cp-patches] FYI: Small font fixes

Hi Mark,

The two open bugs - PR 31539 (ProgressBar) and 28186 (drawString) - were 
still leaking pretty badly after my patch.  Your FontPeer cache fixes 
31539 very nicely, but 28186 is still leaking (maybe it's a jamvm bug, 
since cacao doesn't leak with the same testcase).

The static freetype map patch I just committed is a more "proper" fix 
for ProgressBar, but without the FontPeer cache it still leaks - just 
slower.  This might be a problem inside Pango itself.

Cheers,
Francis
