In a similar way to Position, now specified and computed gradients share
a common Gradient type defined in style::values::generics::image.
This allows us to reuse most code for many style traits like ToCss,
HasViewportPercentage and ToComputedValue.
The test changes are the fallout of the disappearance of AngleOrCorner::None,
which align our code to the spec for serialisation, where components that can
be omitted should be omitted.
Renamed BrowsingContext to WindowProxy in script.
<!-- Please describe your changes on the following line: -->
Renamed `script::dom::BrowsingContext` to `script::dom::WindowProxy`.
The browsing context is mostly maintained in the constellation, not in script. It would be nice to rename `constellation::Frame` to `constellation::BrowsingContext`, but that will be very confusing if there are two `BrowsingContext` types.

explicitly specify bitness for x86 cross-compilation situations
Despite compiling for architecture X, the user may have specified a
clang that defaults to architecture Y. We need to ensure that we invoke
clang with the correct architecture selection. We do not use --target
to do this, however, because that runs into problems with LLVM's default
search paths. For the x86 case, we can simply use -m$BITNESS to select
the correct architecture.
This is not at all a general solution, but it does unblock compiling Stylo for 32-bit Linux on Gecko's infra.

Recalculate font-size when generic changes
With the MathML refactorings this feature got lost. It would still get
recalculated when explicitly specified as a keyword, but not otherwise.
To avoid hitting the font metrics provider too often, we only do this
when the generic changes. Otherwise we trust the existing calculated
font.
I swear, once Stylo lands I'm going to campaign to remove font-size from CSS entirely. 😩

To preserve the previous functionality of delaying load events when a
new navigation is triggered, pending pipeline id represents the
current pending load. The load event is only fired if the load message's
pipeline id matches the pending pipeline id.

This slims down SharedStyleContext, in preparation for a few things.
First, I would like to eventually move the stylist to the document in Servo, in
order for it to hold the StyleSheetSet.
Also, this gets rid of a fair amount of overhead while creating it in stylo.

Fix clamping of scroll position in window.scrollBy
For rightward and downward overflow the spec says:
Let x be max(0, min(x, viewport scrolling area width - viewport width)).
Let y be max(0, min(y, viewport scrolling area height - viewport height)).
Previously, those operations were reversed, which created negative
overflow even when the overflow direction was downward. This change
ensures that Servo matches spec behavior.
