We have about 11,500 of these when loading gmail in a Stylo-enabled build, from
SpecifiedUrls; the objects themselves account for about 1.3 MiB of memory, and the
strings within them about 2.9 MiB.
We also have a very small number of them on the Gecko side.

This property accepts a color. It's inherited and defaults to transparent.
Its value is respected on macOS when rendering text into transparent pixels.
This property should be used for text that is placed on top of "vibrant"
-moz-appearances, in order to achieve high quality text rendering for such text.
In most cases, the property should be set to a named system color; an upcoming
patch in this patch series will add one such color for each vibrant
-moz-appearance value.
However, in some cases it can also be useful to use a custom color: If text
is rendered into an intermediate surface, for example because a mask is applied
to it, and the background color behind that intermediate surface is known, then
this property can be set to that background color in order to achieve subpixel
AA for the text inside the mask effect. In that case, the font smoothing
background color is respected because text is rendered into transparent pixels
*inside the intermediate surface*. At the moment, the only example of that use
case is the text of the active tab in the state where the text is overflowing.

The old code doesn't work because mScriptHandlingObject is a nsWeakPtr,
which cannot be casted to nsPIDOMWindowInner directly.
Since scriptHandlingObject is a strong reference to the same object, we
can just try casting that.

A single transition value that includes 'none' for transition-property is
valid, so we should store whole specified values (if it's valid). Whereas,
the spec [1] clearly says for the case where there are multiple entries;
If there is more than one <single-transition> in the shorthand, and any of
the transitions has none as the <single-transition-property>, then the
declaration is invalid.
'none 2s linear 2s' is a test case for the former, '1s width, 2s none' is a
test case for the latter.
Note that with this patch, 'transition: none' is serialized as 'none 0s ease 0s'
instead of 'none' but it matches Gecko.

This change requires new code to measure HashMaps, which uses the new
'malloc_enclosing_size_of' functions that can measure a heap block from an
interior pointer.
The patch changes MallocSizeOfFn to a newtype, and introduces
MallocEnclosingSizeOfFn alongside.
It also adds new traits: MallocSizeOfBox, MallocSizeOfVec, MallocSizeOfHash.
These each contain a single method that does shallow measurement of the
relevant type, which is often useful. (This is a different style to the
existing MallocSizeOf trait, which does deep measurement, but I'm moving away
from the always-deep-measurement style because it's less flexible.)

The Servo_KeyframesRule_GetKeyframe binding function has been empowerd and
renamed to Servo_KeyframesRule_GetKeyframeAt in the servo side patch. In this
patch, we use Servo_KeyframesRule_GetKeyframeAt to get line and column
information for ServoKeyframeRule, so that the inspector can present Keyframe
rules on the devtool panel properly.

In a number of places, there's no substantial use of maps any more
after the segue.
The ELEMENT segue tries the FragmentOrElement QI, but that is
redundant with the Element QI.
This lets me use a few higher-level macros.

When an animation is newly created while the same property transition is
running, the transition style rule persists until we call RequestRestyle() for
transitions level. That means if user calls getComputedStyle for the property
right after creating animation, the style obtained by getComputedStyle still
included the transitions level rule. As a result, the transitions level style
overrides newly created animation style until the next normal restyling process
happens (i.e. process transition level restyle request). Vice versa, in the
case where an animation is removed, transitions level style does not appear
until the next normal restyling.
This patch fixes this problem by trigerring a resyle of the transitions level
when an animation is created or removed.

Prefixed linear gradients use direction keyword to indicate starting point of the
gradient but modern syntax uses this keyword to indicate ending point of the gradient.
Top-to-bottom direction is the default value for gradients. Therefore `top` is default
value of prefixed linear gradients and `to bottom` is default one for unprefixed one.
For brevity, we omit the direction keyword from our serialization when it matches the
default direction, but we were incorrectly trying to remove `bottom` keyword from
prefixed computed values.

- Adds MOZ_DEFINE_MALLOC_ENCLOSING_SIZE_OF, for defining

- Uses these functions to replace some horrid pointer arithmetic in functions

The change in CounterStyleManager::BuildCounterStyle converts a case-
insensitive comparison to a case-sensitive comparison by comparing atom
pointer directly. But this is fine because all names of builtin counter
styles should have been lowercased by the parser. For Gecko, it is done
in CSSParserImpl::ParseCounterStyleName, and for Servo, it is done in
counter_style::parse_counter_style_name.

Doing this at compile time would save a bit of our startup time, which
I've promised to do since @counter-style was initially implemented, see
bug 966166 comment 103 (the paragraph with "constexpr").
Also, having this implemented here makes using atom instead of string
on name of builtin counter styles easier, for later patches.

nsDocument::GetAnimationController() will lazily create an animation controller
which, in some call sites, is unnecessary.
This patch first calls HasAnimationController() and only calls
GetAnimationController() if it returns true. This avoids creating an animation
controller in situations where one is not necessarily required.

This patch splits up the existing "layout/style-sets" measurement into
"layout/gecko-style-sets", or "layout/servo-style-sets/stylist/rule-tree" and
"layout/servo-style-sets/other". (Additional things will be measured under
"layout/servo-style-sets/" later, such as cascade data.)
This requires introducing a new type, ServoStyleSetSizes, for transferring the
multiple measurements from Rust code to C++ code.
