DOMMatrix needs to convert a specified transform list into a matrix, so
we could rewrite to_transform_3d_matrix by generics for both specified
and computed transform lists.
Besides, we have to update the test case because we use Transform3D<f64> to
compute the matrix, instead of Transform3D<f32>, so the result will be
the same as that in Gecko. Using 0.3 may cause floating point issue
because (0.3f32 as f64) is not equal to 0.3 (i.e. floating point precision
issue), so using 0.25 instead.
Sending scroll positions to Webender is way too flaky to run the
position:sticky tests at this time. We need to disable them for now, so
that other Servo work can continue.
This leverages the position:sticky support in WebRender to bring basic
support for position:sticky in Servo. There are still some issues with
nested sticky flows as well as a few other corner cases. Tests are
imported from WPT and can be removed once we update to the latest
version.
Don't update iframe pipeline until load completes
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.
Track frame size on Frame instead of Pipeline
Disabled matchMedia test
Track creator pipeline id
Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.

Correct viewport test references
These references were using an incorrect value for the expected
container width. Now that WebRender is no longer clipping to stacking
context boundaries the rendered width is correct (100% of viewport
width = 240px).
If a box has a different writing-mode than its containing block, and has a specified display of inline, change the computed display to inline-block.
Also adds the second manual testcase from #15754 as a WPT to assert that the computed display does in fact change.
This includes a WR update that improves pixel snapping. Specifically,
the non-transform shader now snaps to device pixels in world space,
rather than local space.
This makes 31 new tests pass, and adds 4 new failures.
Of the new failures:
- The three background size tests appear to be an OSMesa accuracy
issue. Near the bottom of the image, a small number of pixels
are different from the reference by a value of 1.0 / 255.0. I've
confirmed on 3 real GPUs and also on llvmpipe that the tests
match on those devices. This would be a good case for fuzzy test
support in WPT.
- The other failing test appears to have unreasonable accuracy
requirements as it also fails on Gecko and Chromium in the same
way that the test now fails on WR.

Implement `word-break: keep-all` (#9673)
<!-- Please describe your changes on the following line: -->
Implement the `keep-all` value for the `word-break` property, as specified in [CSS](https://drafts.csswg.org/css-text-3/#word-break-property).
The relevant CSSWG tests (in `tests/wpt/css-tests/css-text-3_dev/html/word-break-keep-all-*.htm`) do not currently pass. As far as I can tell, this is because the tests use some JavaScript code that is not working properly. (But then, it seems that most tests in this directory are failing at the moment. I'm not sure what can be done here for now.)

Since WebRender uses the pipeline ID stored in the iframe element to
determine which pipeline to display, it had better be kept up to date!
Closes#9919.
