zero-width chars are ignored if they're at col 0
...
This can cause a crash, and is impossible since zero-width chars are
always attached to a prior character. Word-wrapping doesn't come into
play here because this check happens prior to the wrapping.

OSC 52: Clipboard Control ( #52 )

This adds support for OSC 52 -- applications can read/write the clipboard. Due to the security risk of this, the default configuration allows for writing but _not reading_. This is configurable using two new settings: `clipboard-read` and `clipboard-write` (both booleans).

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.
