- Moves hair from face-space to global space and back. - Allows for editing of emitter mesh after hair combing. - Disconnect hair before doing topology changing changes in mesh edit mode, connect after changes. - Notes: * The closest location on emitter surface to the hair root is used to connect the hair. * Emitter deflection, sticky roots and add brush don't apply for disconnect hair in particle mode. - Todo for future: * Copy disconnected hair from object to another (when 2.5 has proper copy operators again). * Possible automatic disconnect/connect with topology changing operations in mesh edit mode. Other changes/fixes: - Proper subtypes for some particle mode notifiers. - Particle mode selections didn't draw correctly because of using lighting for the paths.
