CORS only works on http channels, so anything else that tries to do a
CORS-enabled request fails catastrophically.
resource:// images are useful for extension developers, so don't perform CORS
checks on them. We may want to also do file:// and fix bug 1565509, while at it,
if we consider it's causing developer pain.

Currently items are painted with a context that has a transform of
-mLayerBounds.TopLeft(). This means that if TopLeft() changes the commands
will be in the wrong place because the -TopLeft() offset is baked into the
recording.
I don't think we've ever needed to support painting without this transformed
baked in so there were some infrastructure changes that needed to be made to
make this possible. Most of the problems come from the use of
gfxContext::GetClipExtents which expose the bounds of the underlying surface.
The biggest of these was fixed by the CreateClippedDrawTarget rewrite. The rest
should be handled by ensuring that the DrawTarget has bounds that are at least
as big as the union of the individual item bounds. i.e. GetClipExtents should
never intersect with bounds of the item.
This change has a couple of parts:
1. Store mLayerBounds.TopLeft() in the recording so that it will be subtracted
during replay
2. Use mLayerBounds as the Rect of the RecordingDrawTarget
3. Don't include mLayerBounds.TopLeft() in the transform during recording.
4. Adjust the dirty rect by recordingOrigin before we use it as a clip so that
it stays in the right place.
5. In PaintContainerItem the bounds parameter of PushLayer is in device space
so we need to account for the shift in the location of device space in the
DrawTargetRecording.

Update the existing reftests to not use 3 valued syntax.
I run the script to update the syntax in
`layout/reftests/w3c-css/submitted/images3/*`,
`layout/reftests/w3c-css/submitted/masking/*`,
`layout/reftests/xul/*`, and
`layout/reftests/webm-video/*`:
```
function rename() {
find layout/reftests/\

! -path "./.git"\
! -path "./.hg"\
\( -name "*.html" -or\
-name "*.xul" \)\

}
rename "object-position: top 3px center" "object-position: top 3px left 50%"
rename "object-position: center right 25%" "object-position: top 50% right 25%"
```
For `layout/reftests/svg/svg-integration/clip-path/*`, I just manually

The only different part is to resolve intrinsic image size. This patch
implements explicit requirements of the spec, but an edge case is tricky.
It's not clear per spec what the intrinsic image size is for an SVG
without explicit width/height, something like:
<svg>
<image href="data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg'><rect width='40' height='90' fill='red' /></svg>"/>
</svg>
Chrome treats the intrinsic size of the href svg as the default size of
a replaced element (300x150), our image/VectorImage.cpp doesn't resolve
size in this case.
We can handle this particular case in some seperate bug if necessary, I think.

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.

We remove initial x/y offset for nsSVGUtils::GetTransformMatrixInUserSpace
so that it can be used in not-nondisplay context. Previously it was only
used in nondisplay context, where x/y offset is always 0.
Then we use this utility to get the transform matrix to judge whether we need
special care for non-scaling-stroke. The old matrix doesn't account for CSS
transform.

When an SVG is used as a CSS background-image, we previously used the same behavior as
a normal image. It will stretch if the background-size is incompatible with the intrinsic
size of the SVG. This is a webcompat issue.
Now we use the painting destination rect size instead to avoid stretching.

Most rounded rect clips in real content are (a) axis aligned and
(b) have uniform radii.
When these conditions are met, we can run a fast path for clip
mask generation that uses significantly fewer ALU shader ops.
This is not typically a bottleneck on desktop GPUs, but can have
a large performance impact on mobile GPUs (and perhaps low end
integrated GPUs).
The Mali shader analyzer reports the slow path for the rounded
rect clip shader to be 94 cycles per fragment, while the fast
path is 10 cycles.
