At various moments, whether due to timing or layout issues, root layers (iframes) do not have a size and location. We modify the compositor to have all root layers mask to their content boundaries whether they have a frame rect or not. Uninitialized layers have empty boundaries, so they will disappear from the page. We also have to ensure that clicks to not go to areas of layers that are masked away. This fixes issues where ads on github take over the entire viewport.
When finding the layer under a point, take into account clipping
rectangles defined by layers that mask to bounds. This prevents clicks
from being hijacked by masked layers.
Root layers that define the extent of iframes should always mask their
child content. This fixes a bug where root layers without an assigned
size and location do not spill over the entire scene.
The Unicode awareness of `text-transform` is implemented as well as
possible given the Rust standard library's Unicode support. In
particular, the notion of an alphabetic character is used instead of a
letter.
Gecko has a subclass of text run to handle text transforms, but I
implemented this in a simpler way.

Let's build this incrementally. I implemented a `Blob` that can hold a `DOMString`, and has `size` attribute and `slice(...)` method. I'll finish the rest in later PRs.
Bootstrapping automatically downloads new Rust and Cargo snapshots as needed into versioned directories, but do not remove now-unused versions. This is the desired behavior for `git bisect` to be usable.
However, this means that old version keep accumulating, taking up disk space. This adds a mach command to remove snapshots other than the ones currently being used. It is never run automatically.
To be safe, the command defaults to only printing what would be removed, and only removes stuff when run with a `-f` argument.
