function: restore_ripflags <2> -- init
-------------------------------------------
keyboard equivalent: none

The "INIT" button (lower right) saves current
cuts (ripflags, recoverable with UNDO), and then
restores cuts to original state read in from 3D
surface or flat patch.

This leaves any displayed vertex data intact.

All vertices are unmarked.

See "ALL" to undo all cuts, even initially
read-in.
