Description Simon Fraser (smfr) 2010-01-21 12:14:31 PST 
Bug 33927 fixed an issue with plugin widgets caused by the fact that we use tx,ty to position widgets during painting. This is wrong, since tx and ty may be relative to some compositing layer.

The same issue exists with scrollbars, which get repositioned in RenderLayer::positionOverflowControls(). We should update the scrollbar positions eagerly after scrolling, as we do for RenderWidgets.
