It's a pointless abstraction that propagates the obsolete chan terminology,
swaps the order in which the sender and receiver are returned, and hides a
source of panics.
navigation.
Since WebRender uses the pipeline ID stored in the iframe element to
determine which pipeline to display, it had better be kept up to date!
Closes#9919.
In rust-url 1.0 the `Url` struct is going to have private fields, and there
is no way to to create an aribitrary one without going through the parser.
The plugin never had a clear demonstrated performance benefit,
it was made mostly because it was possible and relatively easy at the time.
This changes headless operation to strictly be a runtime option, rather
than a compile-time one. Note that the old headless version still relied
on a display server to support WebGL, while it now requires one all the
time.
Fixes#8573
mozbrowsersecuritychange event
Fixes#8544
No test yet. Is there a way to mock a https connection?
Also, I wish I could use the `HTTPSState` enum instead of a `String` when calling `trigger_mozbrowser_event` (https://github.com/servo/servo/compare/master...paulrouget:securitychange?expand=1#diff-30a18e04d7e0b66aafdf192e416cad44R306) but that would require `constellation_msg.rs` to know about `HTTPSState`, which is defined in `document.rs`, which would add a dependency to `components/msg`. I could define `HTTPSState` somewhere else maybe? Or maybe it's fine to use a `String`. But then, should I use the HTTPSState strings (`"modern/deprecated/none"`) or the mozbrowser strings (`"secure/insecure/broken"`) (as it is now)

Properly propagate changes when range or trees are mutated
Does the same thing as #6817, but storing Range instances directly in their start and end containers.
