handler_before_draw Subroutine

private subroutine handler_before_draw(self, window, t)

Called each frame just before drawing, the scene at time t and the camera placed (see the module documentation): e.g. to move HUD text next to a moving object, or frames. A view following a frame moved here follows it in this frame's drawing (its transform is taken again after); trajectories' points changed here are drawn from the next frame (change them in before_update).
