Fixes#5620.
Fix the TODOs and FIXMEs to comply with the spec.
Add test case for passing invalid invalid labels.
Update test metadata; three test cases have been resolved upstream and
will be fixed whenever the rust-encoding dependency is sufficiently upgraded.
Implementation is alongside that of TypeErrors.
Note: the jsapi codes are reused for our own purposes, namely
distinguishing error_numbers in the get_error_message callback. See
comments in components/script/dom/bindings/error.rs for details.
Some debugging reveals that the send_back_unused_buffers() quite often sends empty vectors back to the paint task. This still incurs a communication overhead though. Instead check that the there actually are buffers to send back.
Basically, the easiest way to describe the effect of this change is "float placement takes line height into account". It didn't before, which could lead to lines overlapping floats or floats taking up too much vertical space.
Improves Wikipedia.

This exposes some other canvas tests which were marked as PASS before. Two strokeRect related tests are fixed by #5612, and lineCap/lineJoin will have an implementation soon.
The current wpt instructions tell users to run `./serve.py`, which doesn't do anything. I've updated the instructions to use `./serve`, which works as advertised (and matches the instructions from web-platform-tests/README.md).
As the float ceiling is relative to the border box, not the margin box,
of the parent flow, top margin must not be included.
This exposed a pre-existing bug whereby margins are discarded if a block
contains only floats and no content, affecting the tests
`float_intrinsic_height.html` and `margins_inside_floats_a.html`. As a
workaround, some invisible content has been added to the bodies of both
tests.

text layout, and unify the inline layout paths for pre- and
normally-formatted text.
This fixes a lot of "jumpiness" and removes the `new_line_pos` stuff.
Closes#2260.
This fixes a bug where styles are not recalculated immediately when an element's hover or focus state changes. I'm not sure how to write an automated test for this. r? @glennw or @pcwalton
