Hangover level at about 3.

- Currently have spinny magenta rectangle around selected score element, but sometimes it can be off the page.
- Score now scrolls to centre selected element.
- Continuing on with problem of music glyphs incorrectly grouped in strings and ballsing up my matching.
- Adding a big fat button for false positives on garbage elements. Done.
- Need to colour found glyphs to figure out what's going on.
- Err.. glyphs in strings doesn't matter since I'm matching each glyph type, not instances of glyphs. Just need to apply match results to glyph instances (and can break up strings where necessary).
- Breaking up glyph runs (strings) might be hard since the positioning of each character is relative to previous chars and is based on funky typography/font stuff.
- Need to allow user to adjust glyph types before setting types of all instances

Hangover still at about 3.
