The data is taken straight from the ISO/IEC 11172-3 standard. For
decoding efficiency the tables are transformed into trees at compile
time using a constexpr approach. That way no runtime initialization is
necessary and decoding can be faster than searching through tables.
The primary benefit of this is that it's unsigned, as you can't have a
negative amount of children. Plus, all the users of child_count expect
it to be size_t.
We now validate that the provided tag names are valid XML tag names,
and otherwise throw an "invalid character" DOM exception.

Since we now honor the CSS font-size values when deciding line box
metrics, we sometimes find ourselves needing to paint text with a bitmap
font into a box that isn't large enough for the glyphs.
As it turns out, it looks a bit better if we just grow the paint rect to
fit the glyphs (instead of painting chopped-off glyphs.) So let's just
do that for now.
If vertical-align is a length value, we lift each line box fragment that
far from the baseline of the line box.
This is rather messy, and we'll have to improve factoring as we add
support for more alignment types.
The purpose of "entering" a box is to collect box model metrics that
apply to content fragments within the box. However, inline-blocks are
special, in that their inner content does not directly participate in
the inline formatting context outside it.
We were neglecting to pop nodes from the box model stack. The metrics
were already being zeroed out when used, but let's not grow the stack
needlessly.
Instead of just the outline, fill them with some semi-transparent color.
Also add tag name, ID, classes and coordinates to the little tooltip.
Finally, use the border box instead of the context box for metrics,
same as other browsers.
Instead of awkwardly visiting and mutating lengths inside StyleValues,
we now simply create a new StyleValue instead.
This fixes an issue where inherited relative lengths could get
absolutized using a parent as reference, and then not having the correct
values when used in a child context.
Note that we implement .elements as a HTMLCollection for now, instead of
the correct HTMLFormControlsCollection subclass. This covers most
use-cases already.

This API now follows the spec a bit more closely, with regards to the
event being dispatched. There are still FIXME's but this is already an
improvement.

There were two things preventing this from working right:
- UIEvents::UIEvent::create() was actually just DOM::Event::create()
- We didn't return the right JavaScript wrapper type for UIEvent
Previously we were only matching elements with *no* text children.
With this patch, we now also allow any number of empty text children to
be present as well.
