OMR + TEXMAPped unofficial file = ???

Some notes about my implementation:
  • I changed BEGIN to START to be consistent with !TEXMAP.
  • I only support START/END, not NEXT.
  • I'm only officially supporting !DATA in MPD files (since that's the whole point).
  • Only one !DATA entry is allowed per 0 FILE entry in the MPD.
  • When parsing the BASE64 text, I ignore any characters that aren't in the BASE64 character set, so a space after the 0 !: shouldn't break my parser.
I have now implemented the projections in the web renderer project (buildinginstructions.js - branch 'texmap' on github)

In order to create this screenshot:

I had to deviate from the specification regarding the V-projection for spherical. Instead of having the plane P2 containing p1, p2 and a point along the normal of P1, P2 is computed using p and the projection from p onto P1.

Should the spec be updated, or are we all implementing this incorrectly?
