Most of them just want GetRootFrame(), and there's no need to explicitly go
through the frame manager for that, we have a handy alias in the shell.
MozReview-Commit-ID: GriEqkasidY
Poking at the frame tree has problems: If we poke in negative (using
eSkipNativeAnonymousContent), as we were doing, we mess up the case where we're
actually _not_ doc-level, and _not_ ::before or ::after. This can't happen for
content documents, but can happen for chrome (since nsDocElementBoxFrame
implements nsIAnonymousContentCreator).
If we poke in positive, as we used to, you get that right, but mess up the
root scrollbar case.
Instead, use a node property to mark doc level anon content. This is a case rare
enough that it seems worth to not steal a node bit.
To recap the failure:
* The initial value of -moz-control-character-visiblity is different on beta
and nightly.
* XUL has a global rule setting -moz-control-character-visibility on the root,
to a value so that it's the initial one on nightly, but the non-initial one
on beta.
* Changes to this property cause a reframe.
* Reframes of a nsIAnonymousContentCreator anon content reframe the container.
* We were failing to inherit correctly for the nsIAnonymousContentCreator
content for the root XUL element on the initial styling, inheriting from the
default computed values instead, since we failed to reach the root element's
primary frame from GetFlattenedTreeParentForDocumentElementNAC ->
AppendDocumentLevelNativeAnonymousContentTo, since the primary frame is set
_after_ processing children.
This seems somewhat risky to change, and inconsistent with any other stuff
the frame constructor does, see bug 973390.
* Given that, the next restyle of the root element, in this case caused due to
the customizable UI, we _found_ the actual correct parent, recomputed the
style, saw that -moz-control-character-visiblity had changed, and reframed.
But we were reframing the whole window, not just the NAC, because of the
fourth bullet point. Reframing the whole window caused us to lose the popup
state (that's bug 1440506).
Worse than that is the fact that given we reframe and reconstruct the
anonymous countent again, we go back to the initial bogus state, just
awaiting for the next restyle to reframe the whole window.
I wish there was a bullet-proof way to test it that isn't just counting reframes
and relying on which properties reframe or not, but due to the nature of
nsIAnonymousContentCreator's NAC, it's not possible in any easy way I can think
of.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the
beginning of the Reflow().
A few Reflow() implementations have Reset() calls at the end which are left
in place by this patch (with an explanatory comment added to each). These
ending Reset()s are only needed for cases where a non-splittable frame
passes its own nsReflowStatus to a child's reflow method. Just in case the
child leaves a "not fully complete" value in the nsReflowStatus, the
non-splittable parent frame must clear out the nsReflowStatus before
returning, so that its own parent doesn't then try to split it.

The failure mode in the attached crashtest is an inconsistency in the flattened
tree. Specifically, we null out mVideoControls in an nsVideoFrame, but defer
the UnbindFromTree call on that NAC element, which measn that its mParent still
points to the nsVideoFrame's mContent. Because all this stuff runs off of script
runners, and the anonymous content destroyer is not guaranteed to run before
other potential script runners, we end up running arbitrary script while the
tree mismatch exists. This script calls back into ProcessPendingRestyles, which
causes trouble.
We could build a separate deferral mechanism, but it's not clear that we actually
need to defer the unbind anymore. The deferred unbind was added in bug 489008,
which predated a lot of simplifications in layout/dom interaction.

Most of this patch is updating a few places that use gfxMatrix to use
the equivalent-but-differently-named functions on MatrixDouble:
- Translate/Rotate/Scale get turned into PreTranslate/PreRotate/PreScale
- Transform(Point) gets turned into TransformPoint(Point)
- gfxMatrix::TransformBounds(gfxRect) gets turned into
gfxRect::TransformBoundsBy(gfxMatrix).
- gfxMatrix::Transform(gfxRect) gets turned into
gfxRect::TransformBy(gfxMatrix).
The last two functions are added in this patch as convenience wrappers
to gfxRect instead of Matrix.h because we don't want Matrix.h to "know"
about gfxRect (to avoid adding gecko dependencies on Moz2D). Once we
turn gfxRect into a typedef for RectDouble these will be eliminated
anyway.

This updates more code that was using RelativeToParent() to use the
stacking context helper's ToRelativeWr* functions instead. This get us
closer to breaking the assumption that the WR stacking context order maps
1:1 to the layer tree structure.
MozReview-Commit-ID: HQrbvCgPOW4
This is needed for the next patch, because the bullet frame WR rendering
code will need a StackingContextHelper to pass to the PushGlyphs call.
It also helps with some of the later patches in this series, when we get
rid of the RelativeToParent calls.

As we are often converting from LayoutDevicePixel to LayerPixel types
in WebRenderDisplayItem code, I added a convenience overload of
RelativeToParent that takes a LayoutDeviceRect and returns a LayerRect,

This is the bulk of the changes.
- DisplayItemScrollClip is removed. Instead, we will have 1) ActiveScrolledRoot
and 2) DisplayItemClipChain.
- ActiveScrolledRoot points to a scroll frame and allows traversing up the
scroll frame chain.
- DisplayItemClipChain is a linked list of clips, each clip being associated
with the ActiveScrolledRoot that moves this clip.
- Each display item has an ActiveScrolledRoot and a clip chain.
- nsDisplayItem::GetClip returns the item of the clip chain that scrolls with
the item's ASR. The separation between "regular clip" and "scroll clips"
mostly goes away.
- Tracking clips in the display list builder's clip state happens very
similarly to how regular clips used to be tracked - there's a clip chain for
content descendants and a clip chain for containing block descendants. These
clip chains are intersected to create the combined clip chain.
- There are strict rules for the ASR of a container item: A container item's
ASR should be the innermost ASR which the item has finite clipped bounds with
respect to.
- At some point in the future, ASRs and AGRs should be reunified, but I haven't
done that yet, because I needed to limit the scope of the change.

This patch rearranges Paint() so that the next nsRenderingContext is created
via the one-arg constructor rather than via the zero-arg constructor + Init().
This means the SetLineWidth(1.0) call in Init() no longer occurs but that's ok;
it was redundant because 1.0 is the default line width in a new gfxContext.
