This more concrete wrapper type can write a prefix the very first time something
is written to it. This allows removing plenty of useless monomorphisations caused
by the former W/SequenceWriter<W> pair of types.

Implement Element::has_css_layout_box()
r? emilio
Here's my initial attempt to fix#19430. It seems surprisingly simple so I am wondering whether I have missed something! (Or maybe it just actually is quite simple...)
Some things I am unsure about:
1. The spec seems vague about what a [CSS layout box](https://drafts.csswg.org/cssom-view/#css-layout-box) actually is. Indeed it says: "The terms CSS layout box and SVG layout box are not currently defined by CSS or SVG."
2. One thing the spec *does* say explicitly is "For the purpose of the requirements in this specification, elements that have a computed value of the display property that is table-column or table-column-group must be considered to have an associated CSS layout box (the column or column group, respectively)." I am unclear about the relevance of this, since [overflow does not apply](https://drafts.csswg.org/css-overflow-3/#overflow-properties) to an [internal table element](https://drafts.csswg.org/css-display-3/#layout-specific-display). Therefore I haven't done anything about this explicitly, but maybe I'm missing some nuance.

Calling scroll() on an element which is not rendered (by a parent with
display: none) would previously cause a crash. In fact, we should
terminate the algorithm
[https://drafts.csswg.org/cssom-view/#dom-element-scroll] at step 10 in
this situation.
The fix hinges on implementing Element::has_css_layout_box() correctly,
rather than just returning true in all cases as we did previously.
Fixes#19430.
This uses floating-point (Layout) coordinates in where possible.
Replace NormalBorder struct with WebRender equivalent.
Remove ToPointF and ToRectF traits.
Convert border RepeatKeyword with ToLayout.
Add some definitions to malloc_size_of for WebRender types.
Implement the create an element for token algorithm

Root sequence<any> params using CustomAutoRooter
<!-- Please describe your changes on the following line: -->
Attempt at https://github.com/servo/servo/issues/16678. At the moment this pulls an external [remove-handle-conv](https://github.com/Xanewok/rust-mozjs/tree/remove-handle-conv) branch for rust-mozjs (removing `FromJSValConvertible` implementation for `HandleValue` and adding one for `*mut JSObject`)
In short, this roots the `sequence<any>` and `sequence<object>` function arguments using `CustomAutoRooter` (introduced in https://github.com/servo/rust-mozjs/pull/382).
As per https://github.com/servo/servo/issues/16678#issuecomment-302224110 the underlying vector contains raw gc thing pointers instead of handles. To do that, this introduces new possible `isMember = "AutoRoot"` value in CodegenRust.py.
The rooted argument is passed to a function wrapped in a `CustomAutoRooterGuard` [RAII root guard](ed5e37a288/src/rust.rs (L586-L588)) (e.g. as `CustomAutoRooterGuard<Vec<JSVal>>`)
I felt quite out of my depth when trying to adapt CodegenRust.py code, so I'd appreciate any help with how can be done better/in a more clean manner.
Also the name `CustomAutoRooterGuard` is quite lengthy, so I'm also open to changing it (`AutoRoot`? `AutoRootGuard`?)

Fixes#19631
Since the addition of timeouts to paint worklets, CSS paint API threads
were failing intermittently because of the timeouts being fired. This is
because the timeouts are quite tight, to account for the 60fps
requirement. Bumping up the timeout threshold for these tests alone is
the easiest solution.
Correctly place images with background-position: center
Add a regression ref test.
See also #19680.

Unify background placement code
Merges the implementations for background-image placement
from gradients and images. Add missing parts and fix bugs.
Now supported are the CSS properties:
* background-attachment (except for local value, see #19650)
* background-clip
* background-origin
* background-position-x/y
* background-repeat
* background-size
It should be noted that backgrounds are not clipped to
rounded border corners.
(This was done before but worked only in simple cases)
See: #19649
This solves the following issues:
closes#19626closes#16657closes#19482 (examples from http://lea.verou.me/css3patterns/ are rendered perfectly but the round border is completely ignored now)
closes#19577
- `./mach build -d` does not report any errors
- `./mach test-tidy` does not report any errors
I enabled a few tests with the first commit but I have written about a dozen manual tests I will try to turn into ref tests either before or after this patch lands.
