This will allow the HTMLMediaElement later to get a handle to the
RenderApi for rendering video frames.
At a later time, all media handling should be moved to its own
thread/process that is communicated with via IPC. At that point this
can be removed again.
Original-patch-by: Sebastian Dröge <sebastian@centricular.com>
Previously, the `tests` feature flag of the `embedder_traits` crate
caused it and every crate recursively depending on it to be built twice.
This feature flag was used to provide a specific set of "resources"
when running tests. Instead, this commits overrides the `main()` function
of the test harness to change resources at runtime before running any test.
This is done by adding a dependency that has `name = "test"` in its
`[lib]` section of `Cargo.toml`. This overrides the crate found by
`extern crate test;` in code generated by `rustc --test`.
Make JNI code more robust and introduce antialiasing option
This throws exceptions in various places. Trying to reduce the amount of unwrap/expect.

Optional backtraces for JS errors and WebGL errors
This adds two new build-time features to enable useful debugging tools when investigating why JS and WebGL content isn't working. They're optional because they're quite heavyweight.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes do not require tests because they're optional developer features.

This will make it more obvious when one source of WebGL performance problems is present.

Update Constellation to track focused BrowsingContext instead of Pipeline
<!-- Please describe your changes on the following line: -->
I need confirmation as to whether I understand this correctly, but I don't think tracking the focused browsing context instead of the pipeline introduces the benefits described in the issue, because if the focused browsing context is an iframe nested in a document that is being changed, we need to change focus to the browsing context whose current document is being changed, i.e. above the currently focused iframe. Is this correct?
However, I think we may be able to save the slightly expensive iteration over a frame tree (which is needed to check if the currently focused browsing context is nested within the one where the page is being loaded) when the [EDIT] focused browsing is the top-level browsing context, as in this case the load doesn't change the focus. I haven't implemented this as I'm unsure whether this is correct.
