48299a53cb layout: Implement most of border-collapse per CSS 2.1 § 17.6.2.
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.

07bc97e3e2 gfx: Implement letter-spacing per CSS 2.1 § 16.4.
The ligature disabling code has been manually verified, but I was unable
to reftest it. (The only way I could think of would be to create an
Ahem-like font with a ligature table, but that would be an awful lot of
work.)

Near as I can tell, the method used to apply the spacing (manually
inserting extra advance post-shaping) matches Gecko.

a4a9a46a87 gfx: Rewrite display list construction to make stacking-contexts more
first-class.

This implements the scheme described here:

    https://groups.google.com/forum/#!topic/mozilla.dev.servo/sZVPSfPVfkg

This commit changes Servo to generate one display list per stacking
context instead of one display list per layer. This is purely a
refactoring; there are no functional changes. Performance is essentially
the same as before. However, there should be numerous future benefits
that this is intended to allow for:

* It makes the code simpler to understand because the "new layer needed"
  vs. "no new layer needed" code paths are more consolidated.

* It makes it easy to support CSS properties that did not fit into our
  previous flat display list model (without unconditionally layerizing
  them):

  o `opacity` should be easy to support because the stacking context
    provides the higher-level grouping of display items to which opacity
    is to be applied.

  o `transform` can be easily supported because the stacking context
    provides a place to stash the transformation matrix. This has the side
    benefit of nicely separating the transformation matrix from the
    clipping regions.

* The `flatten` logic is now O(1) instead of O(n) and now only needs to
  be invoked for pseudo-stacking contexts (right now: just floats),
  instead of for every stacking context.

* Layers are now a proper tree instead of a flat list as far as layout
  is concerned, bringing us closer to a production-quality
  compositing/layers framework.

* This commit opens the door to incremental display list construction at
  the level of stacking contexts.

Future performance improvements could come from optimizing allocation of
display list items, and, of course, incremental display list
construction.

bffaad118e layout: Rewrite clipping to be per-display-item instead of having
a separate `ClipDisplayItem`.

We push down clipping areas during absolute position calculation. This
makes display items into a flat list, improving cache locality. It
dramatically simplifies the code all around.

Because we need to push down clip rects even for absolutely-positioned
children of non-absolutely-positioned flows, this patch alters the
parallel traversal to compute absolute positions for
absolutely-positioned children at the same time it computes absolute
positions for other children. This doesn't seem to break anything either
in theory (since the overall order remains correct) or in practice. It
simplifies the parallel traversal code quite a bit.

See the relevant Gecko bug:

415bbaeb2e Fix dimensionality of Au
Previously, we implemented:

Au * Au -> Au
Au / Au -> Au
Au % Au -> Au

... which are inconsistent. It should be:

Au * Au -> SquaredAu
Au / Au -> i32
Au % Au -> i32

or:

Au * i32 -> Au
Au / i32 -> Au
Au % i32 -> Au

I picked the latter.

Also, the multiplicative identity does not make sense
when multiplication take two different types.
