Details

Traditional scroll wheels scroll in "lines" or "steps". With main thread scrolling, the actual pixel delta that we scroll in response to such a scroll event is determined in EventStateManager::GetScrollAmount and is based on the font size of the scrolled frame.

We need to figure out what to do with these kinds of events when scrolling is handled by APZ. We can of course have them go through the main thread, but then users of traditional mice can't scroll while the page is busy.
I believe dvander fixed this as part of bug 1086162.
