I just had a look at the upstream commandergenius repo, and I see that
pelya made two-finger drags emulate the mouse wheel, in 49b3987 (2014).  We
forked in 2013. There were some other tweaks to the multitouch gesture code.

I also notice that the documentation for RedefinedKeysScreenKb was improved:
# Redefine on-screen keyboard keys to SDL keysyms - 6 keyboard keys + 4
multitouch gestures (zoom in/out and rotate left/right)
RedefinedKeysScreenKb="LALT RETURN KP_PLUS KP_MINUS SPACE DELETE KP_PLUS
KP_MINUS UNDO HELP"
