Add missing css style for image_rendering_auto_a.html
There was a missing image position in the test which caused potentially
wrong comparision of images in basic.list:
!= image_rendering_auto_a.html image_rendering_pixelated_a.html

This should make it somewhat easier to experiment with alternative
representations in the future. To reduce churn, this commit leaves the String
field public, though.
Also, this will allow us to use the default String type to represent the IDL
USVString type, which explicitly forbids unpaired surrogates, ans as such is
a better match to the Rust String type.

Allow retrieving width/height for non-positioned elements
This was causing a bunch of tests in tests/wpt/web-platform-tests/html/semantics/embedded-content/the-canvas-element/size.attributes* to fail. They were returning "auto" instead of the correct size. They still fail because the returned size is off by a few pixels, not sure why yet. But this is more correct and may fix other failing tests.

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.

commit changes this behavior to calculate the insertion point using

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.
