Simple bugfile - with CSS Filter (hardware accelerated)

1. Open font.html (attached).  This file has a single web font with a CSS Filter attached, which forces hardware acceleration
2. Open font-nofilter.html (attached).  This file is identical to the first one, which has the CSS Filter removed
3. Edit font.html to remove the CSS Filter and add another CSS reference that will force hardware acceleration, such as translateZ(0).

The font is jaggy after the hardware acceleration is turned on.  Not reproducible on Mac.  Please see attached screen shots - one is a comparison to other major browsers (IE and Firefox) using the same file, and the other is hardware accelerated vs. non hardware accelerated.
