Mostly renaming for clarity, as the gradient parsing code is a bit hairy.
This also changes -webkit- gradients, which is, I think, the right thing to do
(otherwise I need to give up on the type system and sprinkle parse_non_negatives
around, which would be unfortunate).
I filed https://bugs.chromium.org/p/chromium/issues/detail?id=1008112 on
Chromium still accepting negative radii for those, so will wait to submit the
patch for review until they reply there with their intentions.

We always check StyleWillChangeBits_TRANSFORM bit together with a
transform-like property set, so using WillChangeBits::TRANSFORM bit to
represent all transform-like properties is ok.
However, it seems the new test case works well even if we don't have this
patch. I still add it for individual transform properties to make sure
the test coverage is enough anyway.

Also, update the serialization by the shorter perference because this is
a new feature and using older syntax doesn't make sense.
Besides, use `cssOffset` for web animation IDL attribute name.

This is in the interests of allowing the frontend team to experiment with
switching from XUL grid to CSS grid, without inadvertently changing the
display values for the grid items via css-grid-item blockification.
This patch's new pref is not expected to remain in the codebase for long.
We're just adding it so that the behavior remains the same by default, because
we do currently have some XUL code that inadvertently depends on -moz-box
display values being blockified to 'block'. The plan is for folks to remove
that dependency e.g. by adding explicit 'display:block' styling to frontend
code as-needed. After we've done that, we can tentatively flip the pref to true
by default, and then remove the pref entirely.

1. Add `generics::motion::OffsetPath`, and use specified `Angle` and
computed `Angle` to define specified `OffsetPath` and computed `OffsetPath`.
2. Add `ray` function into `OffsetPath`.
We also tweak the degree from 150deg to 135deg in wpt (e.g.
offset-path-ray-001.html and others) to avoid floating point precision issues.
For example:
```
// offset-path: ray(150deg ...);
// offset-distance: 20px;
matrix:
{
{0.500000 0.866025 0.000000 0.000000},
{-0.866025 0.500000 0.000000 0.000000},
{0.000000 0.000000 1.000000 0.000000},
{10.000000 17.320509 0.000000 1.000000}
}
// rotate(60deg) translate(20px)
matrix:
{
{0.500000 0.866025 0.000000 0.000000},
{-0.866025 0.500000 0.000000 0.000000},
{0.000000 0.000000 1.000000 0.000000},
{10.000000 17.320507 0.000000 1.000000}
}
```
Their translate parts, 17.320509 vs 17.320507, are almost the same (only
tiny difference), which may cause the reftest failed.

These two bugs (bug 1572738 and bug 1572451) are stylo regressions.
When font-family changes, we try to recompute the font-size with a length /
percentage combinations in case the generic family changes, so the user
preferences are kept.
When calc() is involved, we clamp to non-negative too early, via
NonNegativeLength::scale_by.
I think we should generally dump this "try to track font-size across calc()"
thingie, as as various comments note it is not quite perfect, and it's not clear
how it should work in presence of min()/max().
This patch fixes the issue and simplifies code a bit, I may consider removing
this altogether in a follow-up.

It's much nicer.
One nice thing about this is that the new code is subject to the existing
threadedness checking, which identified that several of these should be atomic
because they're accessed off the main thread.

I'm _really_ sorry for the size of the patch. I tried to do this in two steps
but it was a lot of work and pretty ugly.
This patch makes us use cbindgen for grid-template-{rows,columns}, in order to:
* Make us preserve repeat() at computed-value time. This is per spec since
interpolation needs to know about repeat(). Except for subgrid, which did the
repeat expansion at parse-time and was a bit more annoying (plus it doesn't
really animate yet so we don't need it to comply with the spec).
* Tweaks the WPT tests for interpolation to adopt the resolution at:
https://github.com/w3c/csswg-drafts/issues/3503.
Trade-off here, as this patch stands, is that this change makes us use less
long-living memory, since we expand repeat() during layout, but at the cost of a
bit of CPU time during layout (conditional on the property applying though,
which wasn't the case before). It should be very easy to store a cached version
of the template, should this be too hot (I expect it isn't), or to change the
representation in other ways to optimize grid layout code if it's worth it.
Another trade-off: I've used SmallPointerArray to handle line-name merging,
pointing to the individual arrays in the style data, rather than actually
heap-allocating the merged lists. This would also be pretty easy to change
should we measure and see that it's not worth it.
This patch also opens the gate to potentially improving memory usage in some
other ways, by reference-counting line-name lists for example, though I don't
have data that suggests it is worth it.
In general, this patch makes much easier to tweak the internal representation of
the grid style data structures. Overall, I think it's a win, the amount of magic
going on in that mako code was a bit huge; it took a bit to wrap my head around
it.
This patch comments out the style struct size assertions. They will be
uncommented in a follow-up patch which contains some improvements for this type,
which are worth getting reviewed separately.
Also, this patch doesn't remove as much code as I would've hoped for because of
I tried not to change most of the dom/grid code for inspector, but I think a
fair bit of the nsGridContainerFrame.cpp code that collects information for it
can be simplified / de-copy-pasted to some extent. But that was a pre-existing
problem and this patch is already quite massive.

Skip whitespace upfront rather than on each individual branch. The only
difference in behavior is that we would've consumed some extra whitespace in the
error case, but I don't think that matters at all.
We were consuming some extra whitespace as well after the close path command for
example, which wasn't parsing anything.

This was an oversight in bug 1520154. We kept the -moz- version in the specified
value but not the computed value.
That's a very peculiar way of making aliases work. This makes them work
consistently as many other aliases instead.
Also, add an assert that would've caught this much much earlier.

There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
According to this resolved spec issue:
https://github.com/w3c/csswg-drafts/issues/2140,
we retire the 3-valued <position> on
1. `object-position`
2. `perspective-origin`,
3. `mask-position`
4. `circle()` and `ellipse()`
, but still keep the support for `background-position`.
Besides, I simply run this python script to generate the .ini file:
```
s = sys.argv[1] + ".ini"
with open(s, "w") as f:
f.write('[{}]\n'.format(sys.argv[1]))
f.write(' expected: FAIL\n')
f.write(' bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1559276\n')
