-----------
NLA SoC: Scale Operators - Clear (Alt-S) and Apply (Ctrl-A)
These two operators work only on Action-Clip strips.
* Clear (Alt-S) resets the scale of selected strips to 1.0
* Apply (Ctrl-A) applies the scale of the selected strips to their referenced Actions. If this referenced Action is also used by several other strips, a copy of the Action is made, and the scaling is applied to that Action instead.
