fn prop_range(c: &Clip, i: usize) -> Option<(f64, f64)>Expand description
The range the rest of the UI enforces for property i (inspector sliders for the base props,
ParamSpec for effect params), so a value-lane drag cannot write past what a DragValue allows.
None where nothing enforces one: Position X/Y and Rotation are unbounded everywhere, and Volume is
a gain behind a nonlinear dB slider.
ponytail: same property order as curves.rs — move it next to prop_ref if a second caller shows up.
