* SAM 2 tracking: prompt frames in frame order, size-check frame reused (#3030) With several objects prompted on three or more frames, the prompts went to the tracker object by object. The tracker keeps features for two frames, so every prompt after the first object fetched and encoded its frame again. Each prompt frame was also fetched once only to check its size and then fetched again for the encoder. Prompts now go to the tracker in frame order (then object order), and the frame fetched for the size check is handed to the tracker the first time it asks for that frame (up to 256 MB of pixel data kept; beyond that the frame is fetched again as before). Objects do not influence each other, so the results are unchanged. Tests cover the prompt order, one host fetch per prompt frame, the order of several prompts of one object on one frame, and the memory cap.
