Update selected handle types to ensure valid state, e.g. deduce "Auto" types to concrete ones. Thereby sel_flag defines what qualifies as selected. Use when something has changed handle positions.

The caller needs to recalculate handles.

Parameters

sel_flag	The flag (bezt.f1/2/3) value to use to determine selection. Usually SELECT, but may want to use a different one at times (if caller does not operate on selection).
use_handle	Check selection state of individual handles, otherwise always update both handles if the key is selected.

BKE_nurb_handle_calc_ex()

void BKE_nurb_handle_calc_ex	(	BezTriple *	bezt,
		BezTriple *	prev,
		BezTriple *	next,
		const eBezTriple_Flag__Alias	handle_sel_flag,
		const bool	is_fcurve,
		const char	smoothing
	)

Variant of BKE_nurb_handle_calc() that allows calculating based on a different select flag.

Parameters

handle_sel_flag

The flag (bezt.f1/2/3) value to use to determine selection. Usually SELECT, but may want to use a different one at times (if caller does not operate on selection).
