Reduce the blur and spread radius size of a reftest.
In the near future, we'll be changing the blur algorithm in WR.
On native GPUs, this is fine - but on OSMesa, a blur of this
radius and spread is quite slow, and can cause test timeouts
when running with a lot of processes enabled.
Reducing the spread / blur shouldn't affect what this is testing.

Random pipeline closure is less likely to kill pending pipelines.
<!-- Please describe your changes on the following line: -->
Make it less likely for pending pipelines to be randomly killed. Pending pipelines send more messages to the constellation, so at the moment we're skewing to killing pipelines early in their lifetimes.

* scrollLeft/scrollTop returned values of parent or even document root
Only the scroll of the node itself is returned. Otherwise 0.0.
* Scrolling via script had set viewport.
This resulted in other nodes appearing scrolled.
Now scroll_offsets are updated with correct node id.
These bugs caused other odd behavior like both body and
document.documentElement being scrolled or the view for scrolled
elements jumping.
Remove the assert_readonly test and add one to verify that assigning to
CSSStyleRule.style correctly forwards to CSSStyleRule.style.cssText.
We currently test for whether CSSStyleRule.style is read-only by
trying to assign to it; however, the spec has it as actually:
interface CSSStyleRule : CSSRule {
...
[SameObject, PutForwards=cssText] readonly attribute CSSStyleDeclaration style;
};
See: https://drafts.csswg.org/cssom/
The `PutForwards=cssText` means that assigning to CSSStyleRule.style
should actually assign to style.cssText.
Limit visited cascade for reparenting
The specialized cascade flow in `stylist::compute_style_with_inputs` (used with
reparenting) currently computes all properties for visited styles, but we only
need visited-dependent properties.
This adds the cascade flag to reduce the work to visited-dependent properties
only, like we do for the regular cascade flow.

There are two key steps when resolving text styles with `::first-line`:
1. `ResolveStyleForText` computes the initial style of the text via
`Servo_ComputedValues_Inherit`
2. `ReparentStyleContext` is called to update style data when the first line
of text is moved to be a child of the `::first-line` frame
Before this patch, `Servo_ComputedValues_Inherit` would clear out unvisited
rules, but visited styles (with rules inside) were cloned as-is, meaning that
step 1 might leave the text node with a style that has:
* Unvisited rules: None
* Visited rules: Some
When we later go to step 2 and re-parent onto the `::first-line` styles, we try
to cascade with these leftover visited rules. This causes any `::first-line`
styles from our parent to be overridden by these rules which are no longer quite
right for the new frame tree.
In this patch, we resolve this by changing `StyleBuilder::for_inheritance`
(which is used by step 1's `Servo_ComputedValues_Inherit`) to also clear out
visited rules, so that we use the same logic for both unvisited and visited text
styles when reparenting onto the `::first-line` frame.

style: Support more selectors in the style sheet invalidator.
In addition to being able to invalidate just based on local name, this
also adds support for invalidating based on selectors with no ancestor
combinator in them (resulting in a RESTYLE_SELF for those elements that
match).
