- setting leaf bone size to minimum bone size in bone branch
- trying to determine bone orientation from joint matrix

Looks like DAE joint matrix orientation cannot be relied upon as a source for bone direction. It can be axis-aligned or pointing in
totally different direction:

It seems to me the best solution is to add a bone with custom draw type that has no pointing direction, sphere for example. Will code
this after merge!
