Snapping the top-left and bottom-right corners separately can cause a
rectangle to change size when offset by a subpixel amount. Instead, this
patch snaps the top-left corner, then rounds the size to a whole pixel amount,
so any rectangle of a given size will always have the same snapped size.
Fixes#7152.
at the last known good split point, and use it for `white-space:
nowrap`.
Fixes overflowing tables on Wikipedia.
This infrastructure should form the basis of our fix for inline layout
of fragments that don't themselves constitute valid split points. That
will require some more work, however.
Mark some tests as failing on Linux, not just Ubuntu 14.04.
They also fail for me on Archlinux.
(`absolute-replaced-height-007.htm` is disabled anyway, but let’s change it as well for consistency.)

Provide a user stylesheet with an `@font-face` rule for it.
Fix#6195.
Many previously-failing tests now pass, and a few previously-passing now fail.
Among the latter, `font-family-013.htm` and `fonts-013.htm` are testing
that the Ahem font is not used for characters it doesn’t have a glyph for.
They were passing because Ahem was not available at all,
and now fail because we don’t implement font fallback correctly.
The others also use Ahem, but I don’t understand yet what’s going on exactly.
The failing `float-applies-to-*` CSS 2.1 tests never really should have
been passing in the first place; they depend on floats inside
fixed-layout tables working properly, which they don't.
Closes#6078.
Closes#6709.
Closes#6858.
The three tests that are marked as failures are because they use offsetWidth as a dummy to force a layout flush. Now that these exist, they expose an unrelated bug with reflow.
It's not possible to correctly determine during the css cascade whether the container height
is explicitly specified. Additionally, the spec https://drafts.csswg.org/css2/visudet.html#the-height-property
says this should affect the *used* height, rather than the computed height.
This significantly improves the layout in #6643.
Implement getComputedStyle
It's not quite done but can probably be reviewed anyway.
I still need to finish up a few of the ToCss impls, I just got lazy and wanted to make sure things worked.
The computation of the used values is definitely not right, I'm going to investigate that.

Passes some but not all WPT tests. One failure is caused by an issue in codegen for the `DOMPointInit` dictionary, the others by outdated tests: Gecko implements an old version of the spec that overloaded the `DOMPoint` constructor to optionally take an object as the first argument, and made `DOMPointReadOnly` non-constructible.
