Removed unncessary call to dirty() in Document::node_and_heritage_change, since the node is aready dirtied by force_dirty_ancestors().

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.

layout: Avoid flooding the compositor with animation state changes if there are no animations running and no new animations were added.
Avoids compositor jank during scroll.

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.

I can't reproduce locally the failure that produced them, and since the
builds that triggered them are deleted for some reason (like
http://build.servo.org/builders/linux-dev/builds/419), it could be a
good moment to troubleshoot it.
If merged closes#7931
This allows to cleanup resources earlier if they stop being used. Right
now all resources were cleaned up when the context was destroyed, this is
a slightly better approach.
We ignore the possible failure of the send() call, since we don't keep
track of these resources from the `WebGLRenderingContext` structure, so
a texture could be destroyed after the context and give us problems.
Un-boxed ScriptReflow
As per #8238 I changed `layout_interface::Msg::Reflow` to store `ScriptReflow` rather than `Box<ScriptReflow>`
I ran the tests and believe everything passed but this is my first commit to the project so sorry if I messed up the protocol!

Implementing activation behavior for <label>
Attempt to resolve#8179
@Manishearth , could you give me some resources having more information about what each function in `Activatable` does? The code compiles on my machine but I guess a lot more is needed
