Create modifiable group clipping
Add a list of clipping areas to map file using new editor window (enable cl_editorcliptrigger 1)
-These consist of tune zone, trigger id, clip x,y,w&h, disableclipping and rewind (envelopes)
Assign a trigger to groups that you want to change (in group context popup)
Add tune zones as normal
Current ver DDNet server & client load these map fine (but with clipping fixed as default)
Vanilla TW connects to server running these maps also
