In summary:

1.15.0: Drawn label 766 times
1.15.1: Drawn label 833 times

Way to go Behdad!

And we can take down that nasty __muldf3 and __floatsidf in pangocairo
(in the loop in draw_glyphs) with a little magic...The __adddf is a
little tough, though, unless the crenderer->*_offset are both 0, I
don't know how often that is true.

I can look at it once I finish the lround bugfix, integrate pdiff,
finish cairo_rectangle optimizations...oh man.
