Jeff Muizelaar 47eafd52d1 Bug 518172. cairo: Disable the previous_scaled_font cache. r=karlt
Rotated text was sometimes broken because there was a mismatch of
assumptions between cairo and Gecko about how important it was
for the ctm of a scaled_font to match the ctm of a context. This
temporarily fixes the problem by disabling the previous_scaled_font
cache with bug #583035 tracking a more permanent fix.
