TODO [no promises :]

? a frozen drone stops DIN quit! << must fix!
? drone is anchored/launched << DONE DIN51
? center of xform to ~ din window center << DONE DIN51
? move chuck center resets trails if auto trail reset on << DONE DIN51
? gravity track mouse << DONE DIN51
? default trail length << DONE DIN51
? default width, depth on drone arrow visual << DONE DIN51
? range based drone snap to note
? gravity magnitude modulation
? velocity/accel magnitude modulation
? mouse as drone
? ball refraction on mondrian
? ball bounce back on mondrian
? volume beyond board height
    currently clamped to max
? set xform center in addition to find xform center already in DIN

-- xx --

? auto-apply on plugin shouldnt auto apply if there was no change
? separation *= or += instead of abs set
? volume envelope on microtonal keyboard
? bring the plugins to microtonal keyboard
	? create drones on points
	? with phase difference for visual drone modulation
	? move drones thru paths
? mondrian
	? per ball or per edge waveform
	? stereo triggering
