This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

Those changesets which are related to animations introduced in bug 1462497
seems to cause new crashes. I think the first two changesets for the bug fixed
the original crash cases but the last two (i.e. these changesets) introduced
other crashes unfortunately.

This method is not a virtual call, and also looks nicer.
This patch was mostly generated by a Python script, but I manually
cleaned up the code in a few places where statements didn't need to be
split across multiple lines any more.

AnimVal() is a DOM getter, and it flushes animations, which we don't want
in GetBBox() which is called from display list building cide and
FrameLayerBuilder.
Returning a zero-sized viewport in the case there's no shell / pres context.
For now, no other change yet. After this we can start tweaking the ShadowRoot
Stylist setup, and even try to return computed styles without a document \o/.

The core of this change is in gfxContext.*:
- change gfxContext::CurrentMatrix() and gfxContext::SetMatrix() to
return and take a Matrix respectively, instead of converting to
and from a gfxMatrix (which uses doubles). These functions therefore
will now match the native representation of the transform in gfxContext.
- add two new functions CurrentMatrixDouble() and SetMatrixDouble() that
do what the old CurrentMatrix() and SetMatrix() used to do, i.e.
convert between the float matrix and the double matrix.
The rest of the change is just updating the call sites to avoid round-
tripping between floats and doubles where possible. Call sites that are
hard to fix are migrated to the new XXXDouble functions which preserves
the existing behaviour.

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.

There are two callers of nsFilterInstance::PaintFilteredFrame:
1. nsSVGUtils::PaintFrameWithEffects at [1]
This function is used while painting a filtered element on a path which
display item painting is not supported yet, such as drawing elements inside a
indirect painted SVG object, such as a mask, a clipPath or a gradient object.
Let's say we have a masked element, which refers to an SVG mask, and there is
a filtered element inside that SVG mask.
Using nsFilterInstance::PaintFilteredFrame to paint that filtered frame in
the mask, we have to pass a gfxContext and a transform matrix to it. The
transform of the gfxContext 'target' that we pass in consists of a transform
from the referenced frame, of the masked frame, to the masked frame. We also
pass in a transform matrix 'aTransform', this matrix contains a transform
from the the masked frame to the filtered frame in *device units*, which
means it contains css-to-dev-px scaling factor.
2. nsSVGIntegrationUtils::PaintFilter at [2]
This function is used by normal display item painting.
The same, we pass a gfxContext 'context' and a transform matrix 'tm' into
nsFilterInstance::PaintFilteredFrame. The transform matrix of 'context'
consists of a transform from the referenced frame, of the filtered frame,
to this filtered frame, but the scale factor was taken out . The transform
matrix 'tm' we pass in contains scale transform from the referenced frame to
the filtered frame in *device unit*.
Inside nsFilterInstance::PaintFilteredFrame, we treat the transform matrix of
'aCtx' and 'aTransform' as parameters we pass in in #2 caller. So it can be
failed in #1. For example, if the filtered frame inside a masked frame has a
translation transform applied, since that translation was put in 'aTransfrom',
but we only use the scale factor of 'aTransform' in
nsFilterInstance::PaintFilteredFrame, translation factor disappears.
In this patch, I unified the definition of parameters of
nsFilterInstance::PaintFilteredFrame:
1. nsFilterInstance::PaintFilteredFrame(aCtx): the transform matrix of aCtx
should be a transform from the referenced frame to the filtered frame in
*css units*. Originally, the aCtx we passed in #1 is in device units, which
should be fixed; the aCtx we passed in #2 does not even include css scaling
factor, need be fixed too.
2. nsFilterInstance::PaintFilteredFrame(aTransform): this transform matrix
should contain only scaling factor in device units. And I removed it in the
end since I found we can get this value easily right inside the callee.

In nsSVGUtils::GetBBox, we cache fill-gemorty's bbox in ObjectBoundingBoxProperty
of the given frame[1] so that we can just return the cache value without
recomputing bbox. Some new added flags, such as eUseFrameBoundsForOuterSVG,
prevent storing and reusing this cache value. This patch is trying to make this
cache mechanism work again.

When nsSVGUtils::getBBox is called on <use> element:
1. Call from SVGGraphicsElement::getBBox(WebAPI):
According to the spec, getBBox should return the bbox as the union box of
children in user space.
2. Call from mask/ clip-path or filter painting:
Since we want to paint those elements in the coordinate space formed by
<use>(bug 537623), getBBox should return the bbox as the union box of
children in coordinate system of <use>.
Depend on the use case, we return the bbox of an <use> element on different
coordinate system. In this patch, I bring in a new
flag(eInUserSpaceOfUseElement) so that nsSVGUtils::getBBox can return bbox on
different coordinate system accordingly.

One thing to note here is that the Scale function on gfxRect has a
different implementation than that in gfx::Rect which is replacing it.
The former just scales the width/height directly whereas the latter
scales the XMost/YMost and recomputes the width/height.

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.

As I've said before, as module owner I prefer that MOZ_ASSERT_IF not be
used in the module because I consider it to be unreadable. However, a
few uses have crept in, and this patch removes them.
I consider it to be unreadable because the name looks like a name that
uses smalltalk-ish naming conventions, i.e., with a part of the name
corresponding to each parameter, in order. However, the parameters are
in the order opposite the name.
This was written primarily with the vim commands:
:%s/MOZ_ASSERT_IF(\([^,]*\),/MOZ_ASSERT(!\1 ||/
:wn
followed by manual cleanup for indentation and removal of !!.

The DrawResult return was not in fact anything to do with the success or
failure of that method, but was actually passing out a very specific piece of information
about the success or failure of any imagelib drawing that may not have occurred
under the various PaintSVG calls.
The signature of PaintSVG is changed from
DrawResult PaintSVG(...., uint32 flags);
to
void PaintSVG(...., imgDrawingParams& aPackage);
imgDrawingParams wraps DrawResult and imgIContainer::FLAG_* as a pack, pass through
PaintSVG to imagelib draw calls under beneath.
