There is something I don't understand about RenderWidget::paint(). If a Scroll event has moved the ScrollView down by exactly or just slightly more than the height of the RenderWidget shouldPaint() in RenderWidget::paint() will never pass.

In the case of this bug the result is that the windowed plugin does not move when a single scroll event moves the viewport down by the same amount as (or slightly more than) the height of the plugin. 

So doesn't ScrollView need to take account of this somehow?
