Description

After SVN 19635, we expected scrolling to get much slower. However, after a few fixes (see SDK-29057) which completed in SVN 19816, we were expecting to bring this number back up. For the most part, we're pretty good, but for the very first page, we are still almost 25% slower than we were before.

Scrolling by page, 1st page went from about 8 fps to 6.2 fps.

I've tried playing with stageQuality to see if the change from medium to high was causing the regression or setting cacheAsBitmap back to false on the TextFields, but it doesn't look like those bring us back to where we were, and I have a feeling we can improve this pretty low framerate somehow.
