Creates a debugger with no length data. The wires will be a connection
between the bones' heads only. The points will show the bones' heads only
and no dotted line of inter bones connection will be visible.

@param name     the name of the debugger's node
@param armature the armature that will be shown
@param deformingJoints a list of joints
