http://www.iltasanomat.fi for example has some Flash based ads occasionally in the
background (seems like not all the loads get the fullpage background ad).
Scrolling that page is never very fast, but when Flash is disabled
(I'm using CTP), scrolling is very slow. About 30% of FF cpu time goes to stuff
under nsCSSRendering::PaintGradients

I assume we end up using this:

Could we not use gradients if we can't paint them fast enough?
