		int	index
	)

Check if the curve map at the index is identity, that is, does nothing. A curve map is said to be identity if:

The curve mapping uses extrapolation.
Its range is 1.
The slope at its start point is 1.
The slope at its end point is 1.
The number of points is 2.
The start point is at (0, 0).
The end point is at (1, 1). Note that this could return false even if the curve map is identity, this happens in the case when more than 2 points exist in the curve map but all points are collinear.

◆ BKE_curvemapping_premultiply()

void BKE_curvemapping_premultiply	(	struct CurveMapping *	cumap,
		bool	restore
	)

Call when you do images etc, needs restore too. also verifies tables. non-const (these modify the curve).
