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.

'contain:size' just means we should size these elements as if they had no

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.

For elements that have box-sizing:border-box specified, the aspect ratio
calculation code subtracts out border & padding from any specified property
values.
So, when we create a fake "override" specified property value for a flex item
whose main size has been resolved, we need to add in the border and padding to
account for the fact that they're going to be subtracted out later.

All of these tests have an .ini file indicating a failure for at least one of
them right now, in the copy that lives in the WPT harness, because
- they trigger a scrollbar in the WPT harness
...and:
- the scrollbar is a slightly different size in the reference case vs.
in one of the testcases, e.g. due to a tiny margin being honored (or not)
on the final piece of content.
This patch shrinks the content a bit in these test files so that they all fit
in a 400x400 viewport and won't trigger a scrollbar. I expect this should make
them pass in the WPT harness when they make the roundtrip through our
synchronization process.

This patch makes us handle calc with percentages when we can convert to
percentages the same way we handle plain percentages in table layout.
We still treat length + percentage as auto (this matches Blink / WebKit as
well). There's one case we differ with Blink / WebKit, which is calc(% + 0px),
which they'd treat as auto instead of a percentage.
I think this is a bug on them (or at least worth some spec clarification). I
filed https://github.com/w3c/csswg-drafts/issues/3482 for that.
In practice what that'd means for us if the WG decides that Blink / WebKit is
right in that case is that we'd need to keep track of whether the calc()
specifies lengths, and return false from ConvertsToPercent if so.
In any case, nothing that would massively change this patch, and I think enough
of an edge case that is not worth blocking on the CSSWG decision here. Though I
could be convinced otherwise of course.

Note that Firefox doesn't actually match this expectation yet, so I've added a

Also, this patch makes several other improvements to this test:
- remove red background in testcase. This was making the testcase spuriously
fail in Chrome, because Chrome paints (at least) a 1px-tall background-area
on empty buttons, which meant a 1px-tall red area in the testcase vs. a
1px-tall gray area in the reference case.
- clear floats to prevent them from piling up awkwardly.
- use 'vertical-align:top' to turn off baseline alignment in parts of the test
where the testcase has text and the reference case does not (and where we're
not intentionally testing the baseline's influence on layout).

The CSSWG has recently resolved that layout containment
suppress baseline alignment, while size containment does not:
https://github.com/w3c/csswg-drafts/issues/2995
Spec text (https://drafts.csswg.org/css-contain/#containment-layout):
"7. For the purpose of the vertical-align property,
or any other property whose effects need to relate
the position of the containing element's baseline
to something other than its descendants,
the containing element is treated as having no baseline."
And a note in (https://drafts.csswg.org/css-contain/#containment-size):
"Note: size containment does not suppress baseline alignment.
See layout containment for that."
This patch does this change just switching IsContainSize()
by IsLayoutSize() in several places related to baseline alignment
in the source code.
With the patch several WPT tests start to pass. Apart from that,
some of the tests under vendor-imports are updated to follow
the new behavior.

This test is basically a copy of its -001 variant, with some "float:left"
sprinkled around on contained descendants.
Before this patch, this test had an additional arbitrary sizing difference as
compared to the -001 version -- there's one element that arbitrarily has class
"outer" in the -002 test whereas it has class "inner-lg" in the -001 version.
These classes have different sizing characteristics, which makes a difference
to whether scrollbars show up, because this element is not contained (though it
is a layout container itself).
This patch undoes this arbitrary difference and also adds a "float" class to
make it easier to see which elements we've sprinkled float styling onto.

The ceiling was introduced in bug 549190 for improve the consistency of
underline positioning. However, removing ceiling now doesn't seem to
regress the testcases in that bug, probably thanks to improvement in
other part.
The ceiling here causes us to have different font metrics than other
browsers on Windows, and can lead to webcompat issue. We also don't do
this for other backends. So it's probably better removing it in favor
of rounding.
There are several test changes:

height of wrapping div in reference page depends on line height, so a

* 368020-1.html changes result because a slightly different line-height

around the issue.
* 456147.xul is disabled because it compares XUL against HTML page, but
XUL has different approach to position text in its elements than HTML.
Specifically, XUL elements don't seem to respect line height while
HTML elements do. The original line height in the file was probably

fix it in a platform-independent way.
