Mix stacking contexts into the positioned content list
Sometimes positioned content needs to be layered on top of stacking
contexts. The layer synthesis code can do this, but the current design
prevents it because stacking contexts are stored in a separate struct
member. In order to preserve tree order, mix stacking contexts into the
positioned content list, by adding a new StackingContextClass
DisplayItem. Such items do not have a base DisplayItem.
In some ways this simplifies the code, because we no longer have to
have a separate code path in the StackingContextLayerCreator.

Fix several bugs causing the page to reflow on every mouse move event
After all these changes are applied, Hacker News and GitHub only repaint and reflow nodes that actually have hover styles applied when the mouse moves over them.

add get_raw_layout_value (HTMLInputElementHelpers)
This resolves#8107
Previously the index of the insetion point for a password input was
calculated using the scrambled string based on the edit point in the
raw string. That could lead to a wrong position of the caret. This
commit changes this behavior to calculate the insertion point using
the raw string.

This is done in
`HTMLInputElementHelpers::get_insertion_point_index_for_layout`
and relies on a 1:1 mapping of the chars in the raw input to the
scrambled chars (currently bullets) in the password input.
Add a friendly and easy-to-read UI for WPT tests
The idea is that this UI will be installed adhoc by the Servo scripts
for now. Later, after baking for a while in the Servo source tree it
will be upstreamed to the mozlog project itself.

Refactor code dealing with headers of requests and responses #6638
Extract the code in load in http_loader.rs that specifically deals with modifying the headers for a request into a separate function. Extract the code that deals with processing the headers for a response into a separate function. This will enable use by websocket code when starting a websocket connection is refactored out of the content process.

Correct event dispatching for multiple simultaneous touch points
Instead of just converting the mouse into a single "touch" input, Servo can now listen for multi-touch events from Glutin, maintain a list of active touch points, and dispatch events for all of them.

Compute value of float according to position value
According to CSS2 Section 9.7, if 'position' has a value of 'absolute'
or 'fixed' the computed value of 'float' should be 'none'.
This changes the float to a single_keyword_computed which checks the
positioned value of the element to compute the float value.

Make executing synthesized pinch zoom more similar to zoom
Synthesized pinch zoom was removed in #8121 so that this combination of
mouse wheel and key press can be handled by the page. I mistakenly
re-implemented it #8215. In order to preserve synthesized pinch zoom,
which is very useful for testing on desktop computers, have it work
similarly to page zoom except with the ALT key pressed.

Fix the implementation of JSTraceable for RefCell.
The existing implementation could panic; make sure that doesn't
happen by requiring that the contents of a RefCell are trivially
traceable (i.e. the value don't contain any traceable objects).
I'm not sure whether the TriviallyJSTraceable trait is actually
worthwhile; maybe we should just never use RefCell in the DOM.

Adding a reference test where a bigger area than the original element
Adding a reference test where a bigger area than the original element size is defined at script.
To pass, this depends in a fix on rust-azure (i.e. #195). No for commit, we need the rust-azure to land and next update the deps.

Add destructors to some WebGL objects, remove duplicated glutin dependency and try to enable the webgl reftests
The first commit allows to cleanup the gl resources of the webgl task earlier if they aren't being used.
Right now all resources were cleaned up when the context was destroyed, so I think this is
a slightly better approach.
The second commit bumps rust-offscreen-rendering-context to remove the duplicated glutin dependency.
The third one tries to reenable the webgl reftests.
Since the errored builds are deleted, It's the only way I can try to troubleshoot it.
