70b017200a copying selection trims trailing whitespace
This is configurable with `clipboard-trim-trailing-spaces`.

This also fixes a bug where debug builds would crash when copying blank
lines. This never affected release builds.

56de5846f4 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).

f1c69343d3 opengl: copy screen data instead of sharing state
Through benchmarking I've determined this lowers lock contention by
about 50% on the critical data.

b18309187e 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.

7bde20a43d 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.
