I couldn't find the place in the spec where the precise behavior of
`:active` is described, so I don't set it. However, all the machinery to
keep track of its status is in place.
Improves YouTube.
the inline sizes of block formatting contexts are likely to be.
Usually, Web developers set this property on block formatting contexts
in order to avoid running into floats, and we can use this as a
speculation hint.
Fixes the width of the search box on the Google SERPs.
layout: Improve our handling of inline absolute containing blocks.
Several issues are addressed in this commit:
* Inline flows now bubble up their absolute descendants instead of
making the inline flow the containing block for them. (In the future,
we will need to make the inline flow *sometimes* be the containing
block for them, but for now it improves sites to unconditionally
bubble up.)
* Fragments now look at their inline fragment context to determine
whether they are positioned.
* Inline flows now push the stacking-relative position of the absolute
containing block down to their inline-block fragments.
* Inline absolute hypothetical fragments can be containing blocks.
* Fixes the logic in
`containing_block_range_for_flow_surrounding_fragment_at_index`. The
condition to determine whether fragments are positioned was inverted!
* `Descendants`/`AbsDescendants` has been refactored in order to become
more friendly to inline absolute containing blocks in the future.
Improves the inline position of the green drop-down arrow in the Google
SERPs. (The block position is still wrong.)

This is necessary for the devtools "Start Recording Performance" button to
send a message.
(This message is not yet supported, so it leads to
'unexpected message type "startRecording" found for actor "performance4"'.)
Upgrade Rust to nightly 2015-08-10
Still needs snapshot.
Snapshot probably could also work as today's nightly (I wasn't able to download the latest one due to choppy internet), there isn't any plugins churn I know of

Prior to this commit, the script codegen makefile relied on an
intermediary pythonpath.py file that handled python dependencies and
incorporated a couple hacks to get the codegen building working. This
commit removes that intermediary file and attempts to make the script
codegen build process cleaner.
Fix "'PaintWorker' panicked at 'index 0 and/or 4 in `*` do not lie on…
… character boundary" when printing display list.
This whole piece of code seems a bit fragile, but it fixes the immediate problem for now.

Fail on unrecognized debug option
Refs: https://github.com/servo/servo/issues/7142
Ran some basic functional tests:
```
$ ./mach run -d -Z bubble-widths,disable-canvas-aa,trace-layout tests/ref/blur_ref.html
$ ./mach run -d -Z help
Usage: /Users/greg/servo/target/debug/servo debug option,[options,...]
where options include
Options:
bubble-widths Bubble intrinsic widths separately like other engines.
disable-text-aa Disable antialiasing of rendered text.
disable-canvas-aa Disable antialiasing on the HTML canvas element.
dump-flow-tree Print the flow tree after each layout.
dump-display-list Print the display list after each layout.
dump-display-list-json Print the display list in JSON form.
dump-display-list-optimized Print optimized display list (at paint time).
relayout-event Print notifications when there is a relayout.
profile-tasks Instrument each task, writing the output to a file.
show-compositor-borders Paint borders along layer and tile boundaries.
show-fragment-borders Paint borders along fragment boundaries.
show-parallel-paint Overlay tiles with colors showing which thread painted them.
show-parallel-layout Mark which thread laid each flow out with colors.
paint-flashing Overlay repainted areas with a random color.
trace-layout Write layout trace to an external file for debugging.
validate-display-list-geometry Display an error when display list geometry escapes overflow region.
disable-share-style-cache Disable the style sharing cache.
parallel-display-list-building Build display lists in parallel.
replace-surrogates Replace unpaires surrogates in DOM strings with U+FFFD. See https://github.com/servo/servo/issues/6564
gc-profile Log GC passes and their durations.
$ ./mach run -d -Z blah
error: unrecognized debug option: blah
Servo exited with return value 1
```
Didn't check that setting debug flags actually did anything.
Haven't written much Rust so this feels more verbose than necessary.
Added `disable-canvas-aa` to debug options help.
Should DebugOptions struct derive Clone like Opts does?
