OSR2++ work in progress

The geometry for the pitch is a bit different, but as from the user experience it works similarly to the OSR2+.

Actually I compared the original vs the ‘new’ pitch geometry:
OSR2+ pitch +/-45
OSR2++ pitch +41.7/-49.6

The difference is about 1.2 degrees, I guess too little to matter practically.
