float BKE_defvert_array_find_weight_safe	(	const struct MDeformVert *	dvert,
		int	index,
		int	defgroup
	)

Take care with this the rationale is:

if the object has no vertex group. act like vertex group isn't set and return 1.0.
if the vertex group exists but the 'defgroup' isn't found on this vertex, still return 0.0.

This is a bit confusing, just saves some checks from the caller.
