- start_stroke()/finih_stroke() -> begin_stroke()/end_stroke() - process_event_queue() -> process_stroke() - GimpMotionBuffer::motion() -> GimpMotionBuffer::stroke() - add GimpMotionBuffer::hover() and process_hover() - remove push_event_history() and pop_event_queue() from API The thing works like this: - Motion events are continuously fed into the buffer using motion_event() - begin_stroke()/end_stroke() correspond to BUTTON_PRESS/BUTTON_RELEASE, the period between them is a "stroke" - If motion_event() returns TRUE, we request "stroke" signals by calling process_stroke() and "hover" signals by calling process_hover()
