Bugs:

• If you set the screen size to really small, vttest crashes the emulator Zig stack traces are currently broken to debug
• Underline should use freetype underline thickness hint
• Any printing action forces scroll to jump to bottom, this makes it impossible to scroll up while logs are coming in or something

Performance:

• libuv allocates on every read, we should use a read buffer pool
• update cells should only update the changed cells
• for scrollback, investigate using segmented list for sufficiently large scrollback scenarios.
• scrollback: dynamic growth rather than prealloc

Correctness:

• exit in the shell should close the window
• scrollback: reflow on resize
• test wrap against wraptest: https://github.com/mattiase/wraptest
  • automate this in some way

Visual:

• bell

Improvements:

• scrollback: configurable
