[x] Zoom in/out buttons
[x] Scroll wheel should zoom -- or perhaps scrolling should pan, and ctrl-scrolling should zoom? (This is how browsers work, and zoom gestures on trackpads send exactly this WheelEvent... except in Safari.)
[x] Pinch to zoom should always work in pan mode
[x] Pinch to zoom when touch drawing is disabled
[ ] We should have a toggle between
- multiple pens drawing at once
- pinch to zoom and two-finger dragging
[x] Button to return to original 1x zoom
[x] Button to fit contents to screen (with some buffer)

Basic zoom functionality (via buttons) now live!

Maybe cocreate should disable browser's default Ctrl++/- and Ctrl+mouse wheel behavior?
