Set the MOZ_DEBUG_RESTYLE environment variable and every restyle will have
detailed logging printed to stderr. By default, restyles for animations are
not logged; you can include them by also setting MOZ_DEBUG_RESTYLE_ANIMATIONS.
If you wish to limit restyle logging to a particular change, you can call
nsPresContext::StartRestyleLogging() and nsPresContext::StopRestyleLogging()
at appropriate points. (You might want to add a couple of helper methods
temporarily on nsIDocument and then expose them to your page with Web IDL
to make them easier to call.) You do not need to have set MOZ_DEBUG_RESTYLE
for this to work.

This will be necessary when we use the restyle tracker for the
animation-only style flush, because animation-only style flushes need to
update *only* the animation style data and no other style data. Thus
using the RestyleTracker for animation-only style flushes requires that
we do this.

FIXME: Adjust for eRestyle_Force if bug 931668 lands first.
Later patches will add such types that are like eRestyle_Self but that
only replace the style attribute, animation rule, or transition rule.
- When OverflowChangedTracker::Flush() coalesces multiple changes
simultaneously, it was possible to downgrade parent frames from
CHILDREN_AND_PARENT_CHANGED to CHILDREN_CHANGED, resulting in an incomplete
update.
- This patch ensures that the strongest ChangeKind is retained when cascading
up to parent frames.
- OverflowChangedTracker::AddFrame now accepts an enumerated type parameter to
indicate if the overflow areas of children have changed (CHILDREN_CHANGED),
the overflow areas of the children have changed and the parent have changed
(CHILDREN_AND_PARENT_CHANGED), or if only the transform has changed
(TRANSFORM_CHANGED).
- OverflowChangedTracker::Flush no longer falls back to calling
nsIFrame::UpdateOverflow when a frame lacks a PreTransformOverflowAreas
property.
- Added an additional change hint, nsChangeHint_ChildrenOnlyTransform, which
results in TRANSFORM_CHANGED being passed in to
OverflowChangedTracker::AddFrame.
- In nsIFrame::FinishAndStoreOverflow, the passed in overflow is now stored as
the InitialTransformProperty for elements that are IsTransformed().
- Partially corrected Bug 926155, by only calling
OverflowChangedTracker::AddFrame on parents of the sticky element during
StickyScrollContainer::UpdatePositions, using CHILDREN_CHANGED.

This moves restyling management out of nsCSSFrameConstructor (thus
reducing its size), and keeps the restyling code closer together.
This is the first of two big chunks of code moved in this patch series.
A later patch in this series will move related code from nsFrameManager
into the same destination file.
