NO_LIGHT_SUPPORT	Object doesn't use any of the light systems. Should be changed to add a light source to the object.
COMPLEX_LIGHT	Light made with the lighting datums, applying a matrix.
OVERLAY_LIGHT	Light made by masking the lighting darkness plane.
OVERLAY_LIGHT_DIRECTIONAL	Light made by masking the lighting darkness plane, and is directional.
OVERLAY_LIGHT_BEAM	Light made by masking the lighting darkness plane, and is a directionally focused beam.
NONSENSICAL_VALUE	Nonesensical value for light color, used for null checks.
LIGHT_ATTACHED	Is our overlay light source attached to another movable (its loc), meaning that the lighting component should go one level deeper.
LIGHT_FROZEN	Freezes a light in its current state, blocking any attempts at modification
LIGHT_IGNORE_OFFSET	Does this light ignore inherent offsets? (Pixels, transforms, etc)
LIGHTING_HEIGHT_SPACE	light UNDER the floor. primarily used for starlight, shouldn't fuck with this
LIGHTING_HEIGHT_FLOOR	light ON the floor
LIGHTING_HEIGHT	height off the ground of light sources on the pseudo-z-axis, you should probably leave this alone
LIGHTING_ROUND_VALUE	Value used to round lumcounts, values smaller than 1/129 don't matter (if they do, thanks sinking points), greater values will make lighting less precise, but in turn increase performance, VERY SLIGHTLY.
LIGHTING_ICON	icon used for lighting shading effects
LIGHTING_SOFT_THRESHOLD	If the max of the lighting lumcounts of each spectrum drops below this, disable luminosity on the lighting objects. Set to zero to disable soft lighting. Luminosity changes then work if it's lit at all.
LIGHT_RANGE_FIRE	How many tiles standard fires glow.
LIGHTING_NIGHTVISION_THRESHOLD	What counts as being able to see in the dark
LIGHTING_TILE_IS_DARK	The amount of lumcount on a tile for it to be considered dark (used to determine reading and nyctophobia)
EMISSIVE_BLOCK_GENERIC	Uses vis_overlays to leverage caching so that very few new items need to be made for the overlay. For anything that doesn't change outline or opaque area much or at all.
EMISSIVE_BLOCK_UNIQUE	Uses a dedicated render_target object to copy the entire appearance in real time to the blocking layer. For things that can change in appearance a lot from the base state, like humans.
EMISSIVE_BLOCK_NONE	Don't block any emissives. Useful for things like, pieces of paper?
EMISSIVE_COLOR	The color matrix applied to all emissive overlays. Should be solely dependent on alpha and not have RGB overlap with EM_BLOCK_COLOR.
EM_BLOCK_COLOR	The color matrix applied to all emissive blockers. Should be solely dependent on alpha and not have RGB overlap with EMISSIVE_COLOR.
EMISSIVE_APPEARANCE_FLAGS	A set of appearance flags applied to all emissive and emissive blocker overlays. KEEP_APART to prevent parent hooking, KEEP_TOGETHER for children, and we reset the color and alpha of our parent so nothing gets overridden
EM_MASK_MATRIX	The color matrix used to mask out emissive blockers on the emissive plane. Alpha should default to zero, be solely dependent on the RGB value of EMISSIVE_COLOR, and be independent of the RGB value of EM_BLOCK_COLOR.
PARSE_LIGHT_COLOR	Parse the hexadecimal color into lumcounts of each perspective.
