      VirtualFlow calls impl_processCSS(false) heavily. However many times (especially with more care in terms of invalidating CSS) we will have clean CSS for a cell, and we don't actually have to reapply any CSS at all. According to my tests, simply avoiding CSS in such cases where it is clean yields a huge performance improvement -- from 30fps to 50fps on run-tableview-bm.
