We could use this method to convert a TransformList into a Matrix, and
use this matrix for computing distance for Stylo and rendering the transform
for Servo.
This is an equivalent of nsStyleTransformMatrix::ReadTransforms in Gecko.
style: Only store applicable ::before / ::after pseudo styles during the traversal.
This should help memory usage quite a bit.

Remove unused selector visitor argument.
The real win here is avoiding cloning the iterator when nobody actually uses it.

The @font-feature-values declaration identifiers are asci case insensitive.
We should convert all of them to lowercase to be able to reduce the same
declarations. Also gecko stores them as lowercase in gfxFontFeatureValueSet.
Devirtualize CSS error reporting.
This removes a trait object from the path of reporting a CSS error.

Try to update running CSS animations when CSS rules are changed.
In the case where values in CSS rules changed directly by CSSOM, the old
value in the CSS rule block is immediately replaced by the new one. So if
the element, which is applied to the CSS rule, has running animations, the
new value is used during cascading process in animation-only restyle. Thus
in a subsequent normal restyle, we can't tell whether the value in the CSS
rule has changed or not. As a result, transitions may not be triggered
(bug 1393323) and CSS animations may not be cancelled if the updated
animation-name is 'none' (bug 1392851).
For the latter case of CSS animations where animation-name has been updated to
'none', this patch introduces a workaround whereby we trigger an update of
running animations whenever the traversal is triggered by changes to CSS rules
and we have existing CSS animations.

For now, only #[animation(error)] is supported on variants and it makes
both #[derive(Animate)] and #[derive(ComputeSquaredDistance)] ignore
this particular variant.
In the case where values in CSS rules changed directly by CSSOM, the old
value in the CSS rule block is immediately replaced by the new one. So if
the element, which is applied to the CSS rule, has running animations, the
new value is used during cascading process in animation-only restyle. Thus
in a subsequent normal restyle, we can't tell whether the value in the CSS
rule has changed or not. As a result, transitions may not be triggered
(bug 1393323) and CSS animations may not be cancelled if the updated
animation-name is 'none' (this bug).
For the latter case of CSS animations where animation-name has been updated to
'none', this patch introduces a workaround whereby we trigger an update of
running animations whenever the traversal is triggered by changes to CSS rules
and we have existing CSS animations.
Fix the long-standing bug where items that are positioned and have
overflow:scroll or overflow:auto automatically create stacking
contexts. In order to do this we need to fix another bug where display
list sorting can put a Clip or ScrollFrame definition after the first
time it is used in a display list.

Implement CanvasRenderingContext2d.fillText's "unimplemented" message
Basic skeleton for implementing CanvasRenderingContext2d.fillText, only adding methods and parameters in the right place, and a basic test, with some `println!()`.
<!-- Please describe your changes on the following line: -->
This is only the beginning. It were my first couple of hours looking at Rust and Servo.
However, I have _no clue_ how to get the text to render now (basically go from the `println!()` to something else).
It's also possible I messed something up with the `DOMString.parse()` but not entirely sure.
I'm doing this PR as a starting point to get help and learn more about this, _or_ at least maybe save someone some time while implementing this, if no one's able to take the time and show me where/how.
Because it's still a work-in-progress, I'm leaving the boxes below unchecked (even though there are no errors).

First step toward iOS Support
This mostly prevents Gaol/sandboxing to be used during compilation.
There are a number of issues with : `expat-sys`, `servo-freetype-sys`, `fontsan`, `heartbeats-simple-sys`, `mozjs_sys`.
Also modified `components/script/dom/navigatorinfo.rs` in order to add iOS.
```rust
#[cfg(target_os = "ios")]
pub fn Platform() -> DOMString {
DOMString::from("iOS")
}
```
