This is based on the logic in ResponsiveImageSelector::SelectImage (just
simplified because there's no viewport-dependent widths here).

This implements the basic image-set notation without the format()
function (for simplicity).
There's a remaining serialization issue (we should probably skip 1x
resolutions), but that's fine for now, I'll address this in a follow-up
when the feature is testable.
The intention is to do the image selection at computed value time
(keeping a selected index or such), but same, follow-up.
This also fixes an issue where the cors-mode for -moz-image-rect and
cross-fade() was getting ignored when parsing.

This allows supporting image-set(), etc, and simplifies the bullet frame
code significantly, too thanks to two changes:
* Instead of manually managing the image request, use the CSS image
loader, with the `REQUEST_REQUIRES_REFLOW` flag, to handle image
loads correctly. This didn't exist when this code was initially
implemented, but we can nicely use it now.
* Instead of re-implementing another WebRender command-builder thing,
we can just reuse the nsImageRenderer code.

Otherwise on Windows, we have a ColorID::Scrollbar but not any of the other scrollbar part
colors, and the Windows-provided value for Scrollbar doesn't work well
with the default values for the other scrollbar parts that come from the
non-native theme.

Based on the update of github.com/w3c/csswg-drafts/issues/5084,
a 0/0 ratio will serialize as 0/0 in all value stages.

But discard it when backplating behind text, so that text is readable.
This should be uncontroversial... Dealing with widgets is a bit harder
so TBD.

This renames the internal -moz-math-script-level property in order to
prepare for full math-depth support. Currently, the property is guarded
under a disabled-by-default flag, so there should be no observable
behavior change.

This is the first of what will likely be a couple patches for
cross-fade's implementation. Bug 546052 tracks it's complete
implementation.

Forgot to follow up on these two remaining non-standard values that may have
been being used to reset a <meter> or <input type=number> back to its
original appearance, but which telemetry showed no usage of.

This avoids arbitrary precision loss when computing REM units and so on,
which is particularly important if we ever change the base of our app
units (but useful regardless).

The background color for the tree column headers is drawn using the
system APIs, but the foreground uses custom colors, which didn't follow
theme. This can lead to unreadable text with specific colors, e.g.
leading to black on black.
Fix this by using system colors for the foreground as well. It also
adds on-hover styling to match possible background change on hover.
