Strikethrough ( #19 )
...
Not as straightforward as it sounds, but not hard either:
* Read OS/2 sfnt tables from TrueType fonts
* Calculate strikethrough position/thickness (prefer font-advertised if possible, calculate if not)
* Plumb the SGR code through the terminal state -- does not increase cell memory size
* Modify the shader to support it
The shaders are getting pretty nasty after this... there's tons of room for improvement. I chose to follow the existing shader style for this to keep it straightforward but will likely soon refactor the shaders.

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.

get rid of Z buffer stuff
...
This optimization will take more work, and we already got a lot of the
way there by optimizing how we send data down to the GPU.
