Since now most CSS transform related bugs are fixed, it's clear that the
purpose of nsSVGUtils::GetTransformMatrixInUserSpace() should solely be to
replace SVGElement::PrependLocalTransformsTo(eUserSpaceToParent).
After fixing Bug 972041, the only other usecase (Bug 1247218) no longer exists.
OTOH, there is a problem when the parent has a viewbox transform, in that case,
SVGElement::PrependLocalTransformsTo() doesn't include it, but
nsLayoutUtils::GetTransformToAncestor() does.
In fact, it's much easier to compute the transform matrix directly based on
the implementation of nsDisplayTransform::GetResultingTransformMatrixInternal(),
which is also the function internally called by nsLayoutUtils::GetTransformToAncestor().
In particular, we don't need to look at 3D stuff since our matrix is inherently 2D.

Spec quote from https://drafts.csswg.org/css-contain/#containment-size :
"Replaced elements must be treated as having an intrinsic width and height of 0"
To achieve that, we just need to:
(a) make all of these frame classes' GetPrefISize and GetMinISize methods return 0 if they're styled with contain:size.
(b) make all of these frame classes' GetIntrinsicSize() and GetIntrinsicRatio() methods return 0,0.
In some cases, these methods are implemented in terms of common helper methods
(and sometimes member variables). For those cases, this patch adjusts the
helper methods (and variables) rather than the getters themselves.
Also: in one case (nsHTMLCanvasFrame), I needed to update its ComputeSize
method to remove a dependency on the "real" intrinsic size & ratio. I believe
the other classes' ComputeSize implementations do the right thing automatically
by sharing code & data with their intrinsic-size codepaths.

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

With the current code we'll eventually detect the cycle, but will take much
more, creating many shadow trees unnecessarily. Take for example the following:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="133" height="232774">
<style>
symbol { display: block }
</style>
<symbol id="svg-sprite" viewBox="0 0 133 230866">
<title>svg-sprite</title>
<symbol id="svg-sprite" viewBox="0 0 133 230866">
<title>svg-sprite</title>
<use xlink:href="#svg-sprite" width="500" height="500" />
</symbol>
<use xlink:href="#svg-sprite" y="1601" width="133" height="228958" />
</symbol>
<use xlink:href="#svg-sprite" y="1601" width="133" height="230866" />
</svg>
Before this patch, we'd create an svg use element subtree for #svg-sprite. That
subtree will contain two other <use> elements, one under the <symbol>, one not
under it.
Both point to #svg-sprite, but we fail to detect we're an ancestor since the
element #svg-sprite we're looking at is the clone of the #svg-sprite element.
Thus we need to take a look at mOriginal instead (which is the <use> element
under #svg-sprite) rather than at the clone.
Yeah, I had to draw the trees, it's messy :)
Blink and WebKit do something slightly different (they check the element id
directly[1]). That's not 100% correct, since you can have multiple elements with
the same ID.

As it turns out we need this to avoid losing precision both during painting and
during serialization.
This patch also changes to serialize `context-value` if it's the computed value.
I could keep the previous behavior, but it makes no sense to serialize the
initial value. We're the only ones to support this value anyway, and I couldn't
find a definition or spec for this.
Also update tests and expectations for:
* New unexpected passes.
* Always serializing the unit in getComputedStyle.
* Calc and interpolation support.
Chrome also always serializes the unit in getComputedStyle, so I'm pretty sure
this is compatible with them. Chrome is inconsistent and keeps numbers in
specified style, but that's inconsistent with itself and with other quirky
lengths, so I updated the tests instead.

Instead of storing them as LengthPercentage | Number, always store as
LengthPercentage, and use the unitless length quirk to parse numbers instead.
Further cleanups to use the rust representation can happen as a followup, which
will also get rid of the boolean argument (since we can poke at the rust length
itself). That's why I didn't bother to convert it to an enum class yet.
