Contains several commands that can help with testing or debugging.

/exposure debug expose_rgb - makes 3 B&W exposures with red, green and blue filters. Uses camera settings if player holds a Camera in hand.
/exposure debug chromatic_from_last_three_exposures - creates an exposure using chromatic process (combining rgb channels into one image). Uses last 3 exposures from history of the executing player, that are not chromatics themselves.
/exposure debug develop_film_in_hand [keep_original] - develops a Film in player's hand.
/exposure debug clear_rendering_cache - Clears cached images. Probably only be useful to me.
