* Add parser support for 3d transforms.
* Change ComputedMatrix to a representation that suits interpolation.
* Switch stacking contexts to use 4x4 matrices.
The transforms themselves are still converted to 2d and handled by azure for now, but this is a small standalone part that can be landed now to make it easier to review.

This reverts commit 945adabd48.
The CSS Working Group resolved to drop this value from the spec:
http://log.csswg.org/irc.w3.org/css/2015-05-20/#e555680
The group was unable to come up with even a theoretical use case.
Gecko only implemented this value for completeness.
Other browsers vendors have clearly expressed they have no interest
in implementing this.

image fragments.
This also changes the way the placeholder is handled in the image cache
task to decode it up front instead of each time an image fails to load,
both because it was more convenient to implement that way and because
it saves CPU cycles to do so.
This matches the behavior of Gecko and WebKit. It improves the look of
our cached copy of Wikipedia.
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.
`BaseFlow::position` is relative to the parent flow's margin box in the inline
direction. We need to use the parent's `position` as the container size when
translating it to physical coordinates, or we get incorrect results for
non-LTR content.
absolutely-positioned elements.
This also implements a little bit of the infrastructure needed to
support for fragmentation via support for multiple positioned fragments
in one flow.
Improves Google.
Table columns should be layed out according to the 'direction' property of the
table flow, regardless of the 'direction' property of any table-row,
table-rowgroup, etc. flows.
This fixes a number of the `direction-applies-to-*` tests in the CSS2.1 test
suite.
This also simplifies `propagate_column_inline_sizes_to_child` by separating
the code used for table cells from the code for non-cell flows.

computing the intrinsic widths of the associated fragment.
Fixes sites that use spacer gifs for table layout, such as the comments
page on Hacker News.
Improves the Google SERPs.
We mark `html/rendering/replaced-elements/images/space.html` as failing.
This test tested whether `<img hspace>` and inline margins do the same
thing. Since this was trivially the case before (since we implemented
neither) and now is not, this test now fails.
blocks.
* Stop double-counting border and padding for inline-block fragments.
(Test case: `inline_block_border_intrinsic_size_a.html`.)
* Take clearance into account when determining intrinsic widths of
blocks containing floats.
Improves the Amazon headers.
