// tests/stutter_hitch_check.py builds this: runtime/stutter_map.c's hitch rule on made-up frame times, with the few
|
|
// runtime functions it calls stubbed. A steady change of pace (the game drawing at 60 fps after 200) counts no hitch;
|
|
// isolated long frames each count one; a frame over SM_HITCH_SURE_NS counts whatever follows it.
