Blah

Starts some stuff, cleans up other things, but this is mostly to
fix #diagram going off the page
Adds mini version of in-pane examples (click "alt")

- This is generated dynamically so it won't get in the way of the
other stuff so that I don't have to redo it later to show other
people.
- Switched things to using event delegation.
- Found out on hover isn't a thing anymore? On mouseenter/leave.
