Note: The remaining warnings aren't actually problems.

- Use the wheel event instead of the nonstandard mousewheel event.
- Zoom in and out by the same amount (1.1*0.9 is 0.99, not 1).
- Support per-pixel scrolling.

- Replace use of deprecated event.keyCode with event.key.
- Remove some special keys
- Handle normal keys in keydown instead of keypress (doesn't seem to make a difference)

- Add .js extension to imports.
- Inline js-lib/draw/index.js into js-lib/controller.js
- Fix DrawFunction being incorrectly imported from js-lib/draw/function.js as a named import instead of a default import in some files.
- Guard against Safari 10.1 and iOS 10.3 not supporting the nomodule attribute on <script>.

Also cleanup some stray 254 pixel values
