Bugs:

• Underline should use freetype underline thickness hint

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
• test wrap against wraptest: https://github.com/mattiase/wraptest
  • automate this in some way

Improvements:

• scrollback: configurable
• selection on top/bottom should scroll up/down (while extending selection)
• double-click to select a word
• triple-click to select a line
• shift-click and drag to continue selection
• arrow keys do nothing, should send proper codes
• home/end should scroll to top/bottom of scrollback

Major Features:

• Strikethrough
• Emoji
• Ligatures
• Bell
• Mac:
  • Enable retina framebuffer
  • When retina, fonts need to be rendered 2x, they're blurry right now
  • Switch to raw Cocoa and Metal instead of glfw and libuv (major!)
