layout/html/base/src/nsGfxScrollFrame.cpp
- Renamed all occurrences of ScrollPositionChanged() to
to ScrollPositionDidChange() to match changes made
to nsIScrollPositionListener.
- Added ScrollPositionWillChange() stub method.
layout/html/base/src/nsPresShell.cpp
- Added PresShellViewEventListener class that implements the
nsIScrollPositionListener and nsICompositeListener view
interfaces. This allows us to turn caret rendering on and off
when scrolling and repainting to prevent leaving caret cruft
on the screen.
- PresShellViewEventListener is created in InitialReflow(), and
released in ~PresShell().
