float evaluate_time_fmodifiers	(	FModifiersStackStorage *	storage,
		ListBase *	modifiers,
		FCurve *	fcu,
		float	cvalue,
		float	evaltime
	)

Evaluate time modifications imposed by some F-Curve Modifiers.

• This step acts as an optimization to prevent the F-Curve stack being evaluated several times by modifiers requesting the time be modified, as the final result would have required using the modified time
• Modifiers only ever receive the unmodified time, as subsequent modifiers should be working on the 'global' result of the modified curve, not some localized segment, so evaltime gets set to whatever the last time-modifying modifier likes.
• We start from the end of the stack, as only the last one matters for now.

Parameters

fcu	Can be NULL.
