terminal: fix possible crash when increasing columns in resize
...
If a cell has graphemes attached to it, we'd share the grapheme map.
This copies it.

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.

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.

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