- RestyleManager::RecomputePosition now calls
StickyScrollContainer::PositionContinuation with the first continuation
or ib-split-sibling of the passed frame, as PositionContinuations will
update all continuations at once, and expects the first continuation
to be passed in.
This is needed to avoid hitting the assertion "Why did this not get
handled while processing mRestyleRoots?" in CollectRestyles, because we
have a restyle posted for a frame that has the NEEDS_FRAME bit flag set.
- 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 also changes the functionality a little bit to track independent
per-property mutation counts and independent "content active" status.

This patch does the following:
* Move nsIFrame::IntrinsicSize to mozilla::IntrinsicSize so that it can
be forward-declared.
* Move a number of templated inline nsLayoutUtils methods to nsIFrame.
* Use mozilla::layout::FrameChildListID instead of the
nsIFrame::ChildListID typedef in nsLayoutUtils.h.
* Move nsReflowFrameRunnable to its only user, nsProgressMeterFrame.cpp.
* Make a number of functions requiring nsIFrame.h out-of-line.
* Remove the nsIFrame.h #include from nsLayoutUtils.h and add it to the
places which require it implicitly.
This depends on bug 898333 in order to avoid causing:
TEST-UNEXPECTED-FAIL | chrome://mochitests/content/chrome/dom/tests/mochitest/chrome/test_focused_link_scroll.xul | Assertion count 1 is greater than expected range 0-0 assertions.
due to the assertion:
###!!! ASSERTION: Shouldn't be trying to restyle non-elements directly: '!aContent || aContent->IsElement()', file ../../../layout/base/nsStyleChangeList.cpp, line 62
The assertion count change in layout/generic/crashtests/571995.xhtml is
expected because it changes us from having 7 of:
###!!! ASSERTION: Shouldn't be trying to restyle non-elements directly: '!aContent || aContent->IsElement()', file ../../../layout/base/nsStyleChangeList.cpp, line 62
with the stack:
mozilla::ElementRestyler::CaptureChange(nsStyleContext*, nsStyleContext*, nsChangeHint) [layout/base/nsChangeHint.h:191]
mozilla::ElementRestyler::RestyleSelf(nsRestyleHint) [layout/base/RestyleManager.cpp:2304]
to only having one. This is expected since this patch changes
RestyleSelf to only call CaptureChange for the first continuation or
block-in-inline sibling.
