Steps to reproduce:
1. Add a sprite font object
2. Scroll around the layout a bit
<img src="https://dl.dropboxusercontent.com/u/105711543/spritefont_bug.gif" border="0" />
Characters are inverted, stretched, and offset. Happens at random, sometimes to all sprite fonts, sometimes to just a few.
Should be displayed as "Score" is.
