This property determines the background positioning area, that is the position of
the origin of an image specified using the 'background-image' CSS property.
'background-origin' is ignored when background-attachment is fixed.
Spec: http://dev.w3.org/csswg/css-backgrounds-3/#background-originFixes#6045.
Known issues:
* Collapsed borders do not correctly affect the border-box of the table
itself.
* The content widths of all cells in a column and the content height of
all cells in a row is the same in this patch, but not in Gecko and
WebKit.
* Corners are not painted well. The spec does not say what to do here.
* Column spans are not handled well. The spec does not say what to do
here either.
Transition events are not yet supported, and the only animatable
properties are `top`, `right`, `bottom`, and `left`. However, all other
features of transitions are supported. There are no automated tests at
present because I'm not sure how best to test it, but three manual tests
are included.
`cellspacing` attribute per HTML5 § 14.3.9.
Table layout code has been refactored to push the spacing down to
rowgroups and rows; this will aid the implementation of
`border-collapse` as well.
This commit also fixes two nasty issues in table layout:
* In fixed layout, extra space would not be divided among columns that
had auto width but had nonzero minimum width.
* In automatic layout, extra space would be distributed to constrained
columns as well even if unconstrained columns with percentage equal to
zero were present.
§ 12.3-12.5.
Only simple alphabetic and numeric counter styles are supported. (This
is most of them though.)
Although this PR adds a sequential pass to layout, I verified that on
pages that contain a reasonable number of ordered lists (Reddit
`/r/rust`), the time spent in generated content resolution is dwarfed by
the time spent in the parallelizable parts of layout. So I don't expect
this to negatively affect our parallelism expect perhaps in pathological
cases.
`background-size` per CSS-BACKGROUNDS § 3.9.
Nearest neighbor interpolation is used for `crisp-edges`, like Firefox.
A note has been added that we could do better if we wanted to.
Multiple backgrounds are not yet supported.
Rebase of #4368. Fixes#4368.

CSS-TEXT-3 § 7.3.
`text-justify: distribute` is not supported.
The behavior of `text-justify: none` does not seem to match what Firefox
and Chrome do, but it seems to match the spec.
Closes#213.
Avoids duplicated code when implementing the CSS properties accessors in
CSSStyleDeclaration WebIDL. Servo internal CSS properties are not
accessible.
CSS property "float" is unnacessible because we currently lack support
for BinaryName IDL annotation (#4435).
Fixes#4429, #4430.

This reverts commit 8666a37f833b06c3e43f27acd8a9678e94425e55.
This just includes the .webidl file (with some of the functionality
commented out) and the stub implementations for the bindings.
This is another step towards #1721.
