Comment 2 for bug 890221

I've done some profiling recently and found some unnecessary stuff being done on every key press, meaning the next release will be a little bit faster on the average key press.

Rather than the drawing code, the main culprit was re-calculating font sizes for the various size groups. The fake emboss effect didn't appear to do much to the overall performance in my testing, however this may be video driver dependent. If you feel there is a particular system configuration where this is an issue, please post it here. This would help a lot with testing.
