simplify and correct wfs panner Udefs
make static panners compatible with FuncUMapDef
hide expert settings wfsDynamicPoint and wfsDynamicPlane
use UMaps in default presets
rename 'wfsPathPlayer' UMapDef to 'trajectory'
change wfsPath preset name to trajectory

from now on we should start calling WFSPaths trajectories
revise todo list
show paths from UMaps in WFSPositionTracker
add new editing type: WFSRadius

for radius of movements
move point UMaps from Unit Lib and add 'point_noise'
Improve startup VBAP
VBAP - don't load synthdefs of default Udef, write to disk instead
use startPos with the VBAP panners
move 'sync' button on WFSServers window

and remove 'F' and 'R' buttons. Users can now also sync the offline
version to ensure sample-based timing
warn and return 0 if trying to write audio file on GOL system
more intrusive warning for failed audio file export
move pointFromBus to end in argument list of dynamic sources

we want people to use UMaps for this instead. Also removing
indexFromBus in \wfsDynamicIndex; I don't think anyone ever used this,
as there were no control-generating Udefs to feed it.
make WFSMixedView hold a dict of typeDrawFuncs
use WFSRadiusSpec for wfsCirclePath and wfsRandomPath
documentation and renaming of UMapDefs

also removing point_random, not really useful..
even better names for circle and noise UMapDefs
