This works on my simple test page https://people.mozilla.org/~mwu/rem.html , hopefully works on real pages too. Seems a little messy to add root_font_size directly to ComputedValues, but it didn't seem appropriate to add to the style structs.
By "idempotent" I mean that later passes do not stomp on data from
earlier passes, so that we can run the passes individually for
incremental reflow. The main change here was to stop overwriting the
"minimum inline-size" field of each column with the column's computed
inline-size.

`invert` is not yet supported.
Objects that get layers will not yet display outlines properly. This is
because our overflow calculation doesn't take styles into account and
because layers are always anchored to the top left of the border box.
Since fixing this is work that is not related to outline *per se* I'm
leaving that to a followup and making a note in the code.

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.
