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.
This assumes that the specification for how position:sticky behaves for
block-in-inline splits matches the specification for position:relative,
in other words, matches
http://www.w3.org/TR/CSS21/visuren.html#anonymous-block-level .
It's also necessary for patch 9b since the new rule for handling of
style change hints is that a style change hint applies to all
continuations and all block-in-inline siblings ("special siblings").
The change in StickyScrollContainer::GetScrollRanges is really the fix
for bug 918994, but adjusted for the change here to use block-in-inline
siblings ("special siblings") in addition to continuations.
(This is part of the patch stack making change hints apply across all
continuations and block-in-inline siblings. In this case, however, the
change hint only needs to apply once, globally.)
This patch fundamentally makes three changes:
(1) Change the way RestyleSelf is used so that it is called in a loop,
over all of the same-style continuations and block-in-inline
siblings.
(I had a note here reminding myself:
TODO: Don't set hints for descendants!
but I no longer remember what it meant.)
(2) Change the traversal of children to traverse all of the children of
the items traversed in (1).
(3) When traversing children, skip children that are continuations,
since we already reached them in (1) and (2).
A later patch will change the RestyleSelf loop to copy for the later
continuations rather than repeating the work. This will mean reverting
many of the RestyleSelf changes contained here.
Some of the pieces marked temporary will be removed in bug 828312 patch
11, and the rest should hopefully be removed in bug 918064.
Avoiding normalization introduced in bug 895135 caused gradientStart/Stop to
not correspond to the firstStop and lastStop. This can cause us to incorrectly
decide to use the repeat fast path. This patch switches takes us back to the
same condition as we had before the regression.
