annotate src/Voice.cpp @ 23:460c05dd74d0

Various enhancements and code refactorings:
* added some compiler warnings.
* text display is centred and with settable TrueType font
* removed highlight member from Voice state - value is derived from other data
  and passed to Voice::draw()
* Changed voice radius from member to defined constant
* default number of voices is now 4
* adjusted some colours and buffer zone width
* new keyboard commands: reset, quit.
* when keyboard disabled, keys are now passed to server via OSC
* added handlers for various new OSC messages:
  - fullscreen, reset, quit, keyboard enable
  - notify (voice state) : several sub-messages
* call reset and calibrate on window resize (fits triangle to window)
