In the case of an invalid clip-path, the browser is supposed to discard the
mask entirely. In the non-webrender codepath this would happen
implicitly because the computed MaskUsage would have no flags set, and
so no actions would be taken on the gfxContext which contained the
display items rasterized so far. In the WebRender codepath, though, we
invoke the code on a A8 drawtarget that's zero-filled, so if PaintMask
fails to rasterize anything into it, it gets treated as a "mask everything
out" mask. Instead, this patch makes it so that we detect the scenario
where the computed MaskUsage is a no-op, and ensure that we don't apply
the mask in that case.
An alternative approach considered was to initialize the A8 drawtarget to
white instead of black but in cases where there is an actual mask, the
rest of the code assumes it is zero-filled and so that doesn't work.

This was a memory-saving optimization introduced as part of dependencies for bug
686875, but a more general system landed in bug 77999 for Gecko and
https://github.com/servo/servo/pull/18509 for Servo.
So now it's probably even a bit of a pessimization (though probably not huge),
and given this causes bugs like bug 1462742, bug 1157592, and bug 1468145, and
fishiness like the one pointed out in this bug, we may as well remove it.
The performance impact of having to lookup through more rules should be minimal
given the bloom filter and the rule hash optimizations.
This makes me wonder whether we could remove the whole concept of on-demand UA
sheets, since they've caused pain, for example, when the frontend people try
loading <svg>s from NAC (since that triggers sheet loading from frame
construction, which is not good). I'm not concerned about loading mathml.css and
svg.css everywhere, though xul.css may not be as doable since it adds a bunch of
attribute-dependent selectors. Though on the other hand I asserted in the
xul.css code and we don't load it in content with <video> / <input
type="date/time/etc"> and such, afaict, so maybe now that legacy addons are gone
we can remove that sheet from content processes altogether.

-Wmissing-prototypes is a new optional warning available in clang ToT. It warns about global functions that have no previous function declaration (e.g. from an #included header file). These functions can probably be made static (allowing the compiler to better optimize them) or they may be unused.
Confusingly, clang's -Wmissing-prototypes is equivalent to gcc's -Wmissing-declarations, not gcc's -Wmissing-prototypes. A function prototype is a function declaration that specifies the function's argument types. C++ requires that all function declarations specify their argument types, but C does not. As such, gcc's -Wmissing-prototypes is a C-only warning about C functions that have no previous function *prototypes* (with argument types), even if a previous function *declaration* (without argument types) was seen.

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.

Summary:
The implementations of most SVGTextElement methods flush layout when they're
called. Any SVG <text> that is displayed normally will be reflowed by
SVGTextFrame::ReflowSVG, and any <text> that is in displayed SVG but is not
displayed directly (such as <text> under a <defs>) will be reflowed by
SVGTextFrame::ReflowSVGNonDisplayText. Prior to this fix the changed
code always assumed that one of these methods would reflow the text. However,
in the case that the SVG is under an HTML element that isn't itself ever
reflowed (such as if it's under an HTML <caption>) then the SVG text will
not be reflowed either and the invariants of the code are broken.
This patch modifies the functions that implement the SVGTextElement
methods to return an error code if the text has not been reflowed.
Note: I did try to reuse SVGTextFrame::ReflowSVGNonDisplayText in this
case, but I ran into problems. Given that this is an edge case and likely one
than normal authors will never run into I gave up trying to make that work for
now.

nsChangeHint_InvalidateRenderingObservers change hint. There is no need for
these methods to do that again.
nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the

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.

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.

1. Call from SVGGraphicsElement::getBBox(WebAPI):
According to the spec, getBBox should return the bbox as the union box of

Since we want to paint those elements in the coordinate space formed by

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.
