Major ToDos

• Refactor UI code to more easily allow multiple canvas layers (it's partway there already).
• Find user's home directory to save .settings.bin if in direct file system mode.
• Change for..in loops to for..of
  • Partially (mostly?) completed.
• Finish new Babel-based transpiler
• Test Linux support
  • I've not tested the code on Linux since I forked it from All-Shape. I have no idea if it works; I did build it on Linux a few times, but that was a while ago.
• Rewrite server from scratch (node? python? C?)
• Finish de-globalizing code
• Refactor event code.
  • I wrote core/events.js years ago, and it's hideously bad. Needs to be rewritten.
