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.
