a cell is empty only if it also has no styling
...
Previously we only checked if it had no character. With text shaping,
this was causing runs of only empty backgrounds to not render.

Ligatures
...
This introduces a naive first pass at integrating ligatures. The basic
ligatures (such as "==" in some fonts) work great. Skin-toned emoji are
struggling a bit.
This isn't the most performant way to do this, either, and I plan on
improving that.
