070be51910 Implement position: absolute for replaced elements. 
Add reftests for replaced and nested absolute flows.

75f1142107 Implement mini-traversal for absolute flow assign-height. 
This only traverses absolute flows, nothing else.

+ Also, a separate mini-traversal for store overflow.
+ Store descendants with position 'absolute' and 'fixed' in BaseFlow.
+ Bubble up links to absolute and fixed descendants during Flow Construction.
+ Set Rawlink to the CB in absolute descendants.
+ store_overflow() now uses absolute descendants' overflows too.
+ Add reftests for 'absolute' and 'fixed' static y position.
+ Add reftests for overflow (they all fail now).
+ Put absolute flow display items under their CB's ClipDisplayItem.
+ Paint borders in Box_ before the actual box stuff (minor fix in lieu of paint-order).

c4d177a354 Implement position: absolute for non-replaced elements. 
+ Re-implement fixed positioning using the absolute positioning code.
+ Add reftests for absolute positioning and fixed positioning.
+ Refactor assign_widths in BlockFlow to isolate the calculation of
widths and margins.
+ Pass down details of the Containing Block for absolute and fixed flows
during layout. Use it to calculate the static position of absolute flows.
+ Defer calculation of absolute flow dimensions till we build the
display list.

021d32368d auto merge of #1781 : hgentry/servo/mozilla-servo, r=metajack 
Simple change. I hope I'm using github correctly; I'm not too familiar with the PR system. Fixes #1777.

014cf702e4 layout: Rewrite the float context. 
This rewrites the float context to avoid dynamic failures resulting from
`.clone()` misuse. It also renames the float context to the simpler
`Floats`. The new version is modeled on WebKit's `FloatingObjects`.

ffcd3833de Change Text, Comment and ProcessingInstructions parent name from element to characterdata 
All other node's parent type names reflect the actual type of the parent. This change extends that convention to the indicated nodes.

1678cc9a88 layout: Implement basic style sharing. 
No improvement on the rainbow page, but necessary for some other
optimizations we want to do.

758f5ba755 style: Separate out style structs into inherited and initial structs. 
This doesn't make much of a difference in performance, but will be
necessary for style struct sharing.

18c025a8ed layout: Lazily create boxes for whitespace, speculating that they won't 
be needed.

33% win in flow construction on the rainbow page.

d34ebf521d layout: Refactor flow construction to move around large structs less. 
5% perf win, and a net loss in lines of code.

b27f4a8969 layout: Introduce a DOM leaf set as a prerequisite for parallel flow 
construction.

This will be very slow until we have the concurrent hash table, but we
might as well get it in.

e579daefc2 layout: Stop adding flows to the leaf set that are obviously never going 
to be leaves.

60% improvement in flow tree construction time on the rainbow page.

18a2050a64 layout: Port parallel layout over to a generic "work queue" 
infrastructure.

The work queue accepts abstract generic "work units", which in this case
are layout operations. The same speedups have been observed.

5cc744d25d layout: Destroy flows properly under display: none. 
Fixes a crash on http://en.wikipedia.org/wiki/South_China_Sea

It plants a destructor bomb on flows so that this can't happen again.

54f0f17f83 layout: Implement parallel reflow for the bubble-widths and 
assign-heights phases.

This uses the new work-stealing deque. By default, 3/4 of a thread per
logical CPU is used. This can be tuned with the `-y` flag.

I measured a 65% reflow speedup on `perf-rainbow.html` and a 247% reflow
speedup on `http://en.wikipedia.org/wiki/South_China_Sea` on a 4-core
HyperThreaded Core i7. However, numbers were fairly volatile, especially
for the latter.

ee9873bdb5 script: Harden layout a bit more by mostly prohibiting it from seeing 
`AbstractNode` at all.

It can still see it by calling `with_element` for now, although that
needs to be fixed.

Patrick Walton
be69a503fe script: Eliminate the phantom type in favor of just whitelisting methods 
that layout can safely call.

This is simpler. Currently, the set of methods is not safe, but I plan
to lock it down more soon.

4c8383c38b layout: Reference count ComputedValues structures like Gecko does. 
This has no difference in CSS selector matching performance and results
in a 31% speedup in constraint solving on the rainbow page.

dcacab8149 layout: Don't delete non-text boxes from the list of input boxes when 
flushing text clumps. Fixes this page:

    http://en.wikipedia.org/wiki/Yellow_River

This is not the most efficient thing to do; a FIXME has been added
noting what is most correct.

30bbaa49b7 Revert "auto merge of #1356 : ksh8281/servo/remove_@_in_LayoutTask.FontContext, r=pcwalton" 
This reverts commit e8ffac13d7, reversing
changes made to db923feffe.

Reverting this change because FreeType is *not* thread safe. See the
documentation here:

http://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html

"In multi-threaded applications, make sure that the same FT_Library
object or any of its children doesn't get accessed in parallel."

We will need to use a `MutexArc` instead.

dda6d2b53c Convert LayoutContext.image_cache from @mut to MutexArc 
LocalImageCache isn't Freeze so we have to use unsafe_access,
which exists for MutexArc and not RWArc.
