According to the spec, the computed value of transform is as specified, but
with relative lengths converted into absolute lengths, so in Gecko, we do
nothing while computing the value of rotate3d(), and do normalization in
ProcessRotate3D(). If the direction cannot be normalized, we treat it as
an identity matrix.
However, in Servo, we do normalization in to_computed_value(), and looks
like we are trying to normalize any kind of direction vectors, so according
to the spec, let's move the normalization into Fragment::transform_matrix(),
and return an identity matrix if we cannot normalize its direction vector.

Don't clear animation only dirty bit during style recalc
Unless the element is in a display:none subtree.
After bug 1356141, the setup of animation-only dirty bit should have matched
to normal dirty bit's one (Though they don't match in post traversal due to
throttled animation flush). An unset_animation_only_dirty_descendants call
removed in this patch cleared dirty bits which are needed for post traversal if
there is a second animation-only traversal and if there is no need to restyle
for the second animation-only traversal.
The reftest in this patch fails without either this fix or the fix for bug
1367975.

move stylo_test build script guts from Python to Rust
stylo_test's build script is split between Python and Rust. style's
build script already has to perform complicated dances to determine an
appropriate binary to execute, depending on the platform. To avoid
copying and pasting that code, it seems reasonable to simply port the
Python code into Rust, thus making the relationship between generated
files and the cargo dependency output clearer. The new Rust is somewhat
more verbose, but not terribly so.
Doing this makes running `stylo_test` on Windows somewhat easier, as
we don't have to care about the particulars of Python executables. And
more Rust is more better.

stylo: Bug 1374233 - Clamp interpolated values for properties which need to be restricted
Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

Avoid adding id selectors that are in the rule hash keyed by that ID to the list

This partially fixes bug 1369611 (we could look at the rule hash itself to avoid
inserting some more into the list of revalidation selectors).
