mj2_video_target::set_frame_period

Sets the number of ticks of the current time scale (as set by set_timescale) between frames. The frame period may be changed at any point, but an initial value must be set before the first call to open_image. If the video is interlaced, the frame period refers to the complete interlaced frame, with each image (field) occupying half of the total frame period. If the frame period is changed part way into a frame, the value installed when the frame is first commenced is the one used for that frame.
