(Whiteboard: [gfx-noted])
In bug 1470267, we started storing the visual viewport offset in nsIPresShell, in a field called mVisualViewportOffset.
In bug 1471708, we renamed nsIPresShell::mScrollPositionClampingScrollPortSize to mVisualViewportSize.
This offset and size are conceptually part of the same quantity, the visual viewport rect. We should reflect this by storing them together as a rect.
However, currently these quantities are computed and set independently by different pieces of code. If we do combine them into the rect, we should make sure that the entire rect has a sensible value at all times.
