This change fixes the code so that it does not assume that frames with the
NS_FRAME_SVG_LAYOUT bit set implement nsISVGChildFrame. This assumption is
incorrect since there are many SVG frame types that do not inherit
nsISVGChildFrame (such as nsSVGGradientFrame).

I introduced ComputeTargetBBoxInFilterSpace[1] function in bug 1287492.
Two reasons that I think we should not clip filter boundary by viewport
in that function:
1. The patch in bug 1336480 can also fix bug 1287492 and is more correct.
2. That restriction cause wrong rendering result
In this bug, reporter apply filter onto a path object in pattern element.
Before the clipping applied in [1], the boundary of filter effects region is
(x=-1, y=-1, width=10, height=10) in CSS units
After clipping by svg viewport, the boundary turns out to be
(x=0, y=0, width=9, height=9) in CSS units
which is smaller then we need for filter painting. So we should stop clip the
boundary by svg viewport. (Please refer to filter-in-pattern-02.svg in the next
patch).

There are two places that use nsFilterInstance::PaintFilteredFrame. One is
nsSVGIntegrationUtil::PaintFilter, we do take care of it in bug 1224207.
Another path is at nsSVGUtils::PaintFrameWithEffects, apparently I missed that
path while working on bug 1224207.

This is a bug from https://hg.mozilla.org/mozilla-central/rev/2d171d75b746 (bug 1157546). It took a shortcut in trying to get around one of the downsides of tracking visibility on frames instead of content nodes.
We cannot get our primary frame during FrameCreate calls because FrameCreate is called during the frame's Init() function, which happens before the primary frame pointer is set.
So when TrackImage is called from FrameCreate |frame| will be null but mFrameCreateCalled will be true. So we won't hit the early return that tries to detect nonvisible images.
The comment being removed is just wrong. We can obtain a frame for <feImage> just as well as any other image type.
The thing that is different about <feImage> is that it calls IncApproximateVisibleCount() followed by FrameCreated() in the frame's Init() function. This means that the frame is marked visible at the time of the FrameCreated, and there will be no further calls to TrackImage (because there are no further changes). So the FrameCreated call is the last chance to mark this image visible. The regressing changeset tries to get around this by just considering the image visible whenever we know a frame exists (because of mFrameCreateCalled) but can't access it. This ends up affecting all types of images, not just <feImage>.
The above paragraph is also true for SVG <image> that are non-display.
This function is not a virtual function and always returns CAIRO_STATUS_SUCCESS
after the patch in bug 1054838 landed. There is no reason to keep it anymore.

According to bug 1345853 comment 5, tn said:
You probably want to return whatever was drawn there regardless of the
DrawResult. SVGMaskFrame has the same problem. Keep in mind that DrawResult is
only reporting on how drawing of any images went, not the drawing of anything
else. Also looking over the patches from bug 1258510 I see a couple places where
BAD_ARGS is returned if the transform matrix is singular. We would want to
return SUCCESS in that case I think, because we drew what we were instructed to
draw.

I did many change in many files in this patch. But the goal is pretty simple: To
pass the return value of nsSVGPatternFrame::PaintPattern back to the caller
(nsDisplaySVGGeometry). My suggestion is to review this patch right from
nsSVGPatternFrame.cpp.
I made two mistakes in bug 1258510
1. We should not return directly at [1]. RemoveStateBits at l418 will be skip.
2. nsSVGPatternFrame::PaintPattern should return both SourceSurface and draw
result, so that we can update UpdateDrawResult in display item.
All the other changes are to
1. make sure the return value of nsSVGPatternFrame::PaintPattern goes back to
nsDisplaySVGGeometry::Paint correctly.
2. Since the return value of nsSVGPatternFrame::PaintPattern change, we need
modify all existed callers.
I also filed bug 1346124 for handle the returning value of PaintMarkers.

Specifically:
- SVGGeometryFrame.cpp has several uses the type SVGGeometryElement which is
really mozilla::dom::SVGGeometryElement. So I'm adding a 'using' decl for
the 'mozilla::dom' namespace (and I'm dropping a now-unnecessary explicit
dom:: prefix from another type there).
- SVGImageContext.cpp calls several functions on nsIFrame (PresContext() &
StyleSVG() at least). So I'm adding an #include for nsIFrame.h.
- nsSVGMarkerFrame.cpp uses the type SVGGeometryFrame, which is really
mozilla::SVGGeometryFrame. So I'm adding a 'using' decl for
the 'mozilla' namespace.

These only build successfully (in unified mode) right now because they're lucky
enough to pick up a "using namespace mozilla;" declaration from a .cpp file
earlier in their unified compilation unit.

SVG <image> elements have approximately the same level of visibility tracking as regular html <img>s so we shouldn't need to do sync decode. It shows up in some profiles.
The comment being removed was written a long time ago, before image visibility tracking for one.
We could even go a step further and ask for no sync decoding at all, but one step at a time to make sure this doesn't cause any regressions.
This patch is written by the following script with some manual adjustment to
the comment in nsRubyTextContainerFrame.cpp and nsRubyFrame.cpp, and
nsColumnSetFrame's constructor.
function rename() {
find layout\
-type f\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -r "s/$1/$2/g" "{}" \;
}
rename "nsReflowStatus *([a-zA-Z0-9]*) = NS_FRAME_COMPLETE" "nsReflowStatus \1"
rename "([a-zA-Z0-9.*]*) *= NS_FRAME_COMPLETE;" "\1.Reset();"
rename "([a-zA-Z0-9.*]*) == NS_FRAME_COMPLETE" "\1.IsEmpty()"

There is no need to limit output space bounds in
nsFilterInstance::OutputFilterSpaceBounds(), it's just far too early.

For a table, the primary frame is the table wrapper anonymous box. That
anonymous box inherits style from its _child_ table frame, which is the frame that
has the actual style for the element. So we want to use the stylo-computed
style for the table frame, and then compute an updated style for the table
wrapper too, because some things (like absolute positioning) are done for the
table wrapper anonymous box, not the table frame.
