Instead of the potentially adjusted ones. Otherwise, if config_props() is called again and if using force_original_aspect_ratio, the already adjusted values could be altered again. Example command line scale=size=1920x1000:force_original_aspect_ratio=decrease:force_divisible_by=2 user value 1920x1000 -> 1920x798 on init_dict() -> 1918x798 on frame change when eval_mode == EVAL_MODE_INIT, which after e645a1ddb9 could be at the very first frame.
