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.

Both Servo and Gecko store the specified value of the image-orientation
property as a single-precision float, but Gecko does the conversion to radians
and the computation to identify which quarter-turn the angle is closest to
using doubles.
We add Angle::radians64 to perform the conversion to radians using doubles,
just as Gecko does, and then update image_orientation to perform the
computation the same exact way Gecko does in
nsStyleImageOrientation::CreateAsAngleAndFlip. This lets the previously failing
reftests pass.
We also update Gecko_SetImageOrientation to take an orientation directly
instead of an angle (otherwise we'd be doing the which-quarter-turn-is-closest
computation twice).
Finally this lets us re-enable the reftests for image-orientation previously
marked as fails-if(styloVsGecko||stylo).

Previously we just took the input angle mod 2π, which will leave negative input
angles as negative. By checking if the input mod 2π is negative and if so
adding 2π and then taking that mod 2π again we can ensure that we end up with a
an angle in the range [0, 2π].
We only do this if the result of the initial mod is negative because this adds
rounding error that is enough to mess up whether 135 is determined to be closer
to 90 or 180, for example.
We add a test for this as well.
Also fix property_database.js to account for this (we assert that -90deg should
compute to the same value as the initial value, but it should actually compute
to 270deg).

This change does the following:
* Introduce a new smart pointer called CounterStylePtr which either
holds an AnonymousCounterStyle strongly, or a named CounterStyle
managed by CounterStyleManager weakly, and use it to replace all
RefPtr<CounterStyle> around the codebase.
* Rename CounterStyleManager::mCacheTable to mStyles to reflect the
fact that it is used to manage all styles, not just for caching.
* Add a retired styles list which collect all named CounterStyle
evicted from mStyles, and post a PostRefreshObserver to destroy
objects in that list after next flush.
* Remove helper functions for counter style in nsStyleList and expose
mCounterStyle directly, to make code simpler with the new pointer.
Reason for adding a new smart pointer type rather than making their
AddRef/Release behave like BuiltinCounterStyle is that, it is possible
that after a flush, some stale style structs may still be alive. They
can contain pointer to destroyed CounterStyle objects. Although the
actual content may never be accessed anymore, RefPtr may still access
the object for refcounting during destruction.

This patch implement several things:
1. Implement a new constructor for nsStyleImageRequest to receive an existing
ImageValue from the caller.
2. Implement Gecko_ImageValue_Create to allow stylo to create a gecko::ImageValue
object.
3. Implement Gecko_SetXXXXImageValue to allow stylo to pass a created ImageValue
back to gecko.

We need an FFI, Gecko_StyleTransition_SetUnsupportedProperty, to set the
mProperty and mUnknownProperty of StyleTransition. In Servo, we put
non-animatable, custom, and unrecognized property together, so this FFI
should look up the nsCSSPropertyID of the input string, and then store the
value and the unknown property string (if any) back to StyleTransition.

1. add binding functions for -moz-border-*-colors support.
In Gecko, we use double pointers to nsBorderColors to store -moz-border-*-colors.
The computed values of -moz-border-*-colors are set by couple member functions.
To pass the computed value from Servo to Gecko, we need support for these member
functions as well. So, I'm adding some binding functions in this patch. The
actual use of these bindings to pass/store the computed values is separated
in the following patch, which should be a pure Servo change. See servo PR:
https://github.com/servo/servo/pull/16586.
2. update test expectations for -moz-border-*-colors support.
Note that with the support of -moz-border-*-colors, 165 mochitests and 17 reftests
could be fixed.

This switches over from using nsStringBuffer to nsString for URLValueData's
|mString| member. This avoids various tedious conversions and can provide
potential performance improvements by avoiding length calculations.

Now, remove Layer::mSourceURI, there are several benefit of doing this:
1. Reduce the size of nsStyleImage::Layer.
2. By storing style image and url information in nsStyleImage, we can remove
many verbose comments. That is becasue there is no need to explain why we use
mSourceURI here, or why we use nsStyleImage there anymore.
3. Since all inforamtion is stored in on place, nsStyleImage, we can setup image
request or URLs by one single Gecko_SetUrlImageValue call.

This patch implements two things:
1. Add one extra type, nsStyleImageType::eStyleImageType_Url, and puts data of
this type in nsStyleImage::mUrlData.
2. Export SetURLValueData and GetURLValueData from nsStyleImage
With these chnages, we can simply use nsStyleImage::mUrlData to replace
Layer::mSourceURI in the next patch.
