Anonymous tables should not use legacy pseudos, as the legacy layout
engine had them inherit lots of random properites that lead to bad
layout in the new layout engine.

* fix: add font context default in other platforms
When exiting after load or dumping a screenshot, limit the speed that
the compositor sends tick events to the constellation (and on to the
script thread). Previously, these tick messages were sent as fast as the
winit event loop (that's really fast!), until the document was ready to
for its screenshot. rAf is meant to run at more or less the same
frequency as the refresh rate of the screen.
On my system, the massive amount of ticks was overwhelming the router
thread, preventing fonts from loading properly. This change is an attempt
to make tests with requestAnimationFrame less flaky.
* compositor: Improve the way we wait for frames
In the newest version of WebRender it will be harder to make the
distinction between frame queued for scrolling and other kinds of
pending frames. This change makes it so that we queue frames for both
kinds of changes the same way and keeps a counting of pending frames.
This is conceptually a lot simpler.
In addition, do queue a composite even when recomposite isn't necessary
for a WebRender frame when there are active requestAnimationFrame
callbacks. Doing a composite is what triggers the callbacks to actually
run in the script thread! I believe this was a bug, but the WebRender
upgrade made it much more obvious.
These changes are in preparation for the WebRender upgrade.
* Remove spurious println
* Add basic support for enumerating computed styles
The old code was so broken, it was enumerating the style attribute
instead of the computed styles.
So this patch implements a basic enumeration, but not including custom
properties whose computed value is not the guaranteed-invalid value.
* Feedback
The min-content size of a table track was >= the max-content size. So
- For the min-content size of a column, now we just use min-inline-size,
ignoring inline-size and max-inline-size. This matches Gecko, Blink
and WebKit.
- For the max-content size of a column, we keep matching Gecko.
Note that Blink and WebKit are different, they ignore max-inline-size.
- For both the min-content and max-content sizes of a row, now we just
use block-size. This matches Gecko, Blink and WebKit.
Also, if the computed value contains percentages, now we treat it as
the initial value, instead of resolving percentages against zero.
This matches Gecko and Blink, but not WebKit for rows.
* Treat indefinite percentages as auto offsets in relative positioning
Instead of just resolving the percentages against zero.
The spec is not clear (https://github.com/w3c/csswg-drafts/issues/9353),
but this way we match Gecko, Blink and WebKit.
* Update test expectations
* Fix size of tables in flow layout
The contents of a table can make it bigger than what we would expect
from its 'width', 'min-width', 'height' and ' min-height' properties.
Also, 'width: auto' doesn't stretch it to fill the containing block.
We had to refactor the resolution of margins to happen after layout,
otherwise 'auto' margins wouldn't align correctly.

This change adds a version of row height distribution that follows the
distribtuion algorithm used for tables in Blink's LayoutNG. This is just
an intermediate step toward implementing a distribution algorithm for
both rows and columns more similar to Layout NG.
The CSS Table 3 specification is often wrong with regard to web
compatability, which is why we have abandoned it in favor of the Layout
NG algorithm for row height distribution. this work.

This fixed#31438. When an image is loaded from cache, it will
load a placeholder if the url is not a valid image url. This
may be unexpected when using the image cache and specifying
UsePlaceholder::No but that has no effect on loading an image
not in the cache.

Synthetic small caps is supported by the font subsystem, but this is
disabled in Layout 2020. We can turn this on to bring support to parity
with the old layout system.
In addition to turning on synthetic small-caps this change also improves
the way that they work. Before, synthetic small caps meant that every
character was a small version of capitalized character. After this
change, capital letters are larger than small caps versions of small
letters -- matching other browsers and the common expectation of how
small caps works.
We can use stable rust if we pass the unstable configuration as
command-line arguments to rustfmt itself. This prevents needing to
install an unstable rust toolchain.
The one downside here is that it doesn't seem that "ignore" is
supported so we have to start formatting the files in "third_party."
This shouldn't be a huge issue because we don't plan to check much more
rust code into those directories.

In quirks mode, preserved segment breaks should add line height to
lines. This matches the behavior of WebKit and Blink, but not Gecko.
This also handles the special-case of `<br>` elements, which are
implemented with preserved segment breaks via `white-space: pre-line`.
This is an implementation detail though because `<br>` has a special
behavior if the line isn't empty -- it doesn't add any line height in
this case.
