34// Technical note:
35//
36// Most of these functions are identical, converting to Quaternions
37// and then taking the simple distance between two Quaternions. This
38// makes it tempting to use a template function (which could appear in
39// each individual rotation header).
40//
41// However, then we would have to include Quaternion.h in this header,
42// and by induction, each rotation class would depend on Quaternion, which
43// would be undesirable.
