SEETHROUGH_PLANE	Slightly above the game plane but does not catch mouse clicks. Useful for certain visuals that should be clicked through, like seethrough trees
LIGHTING_PLANE	Normal 1 per turf dynamic lighting underlays
O_LIGHTING_VISUAL_PLANE	Lighting objects that are "free floating"
EMISSIVE_RENDER_PLATE	This plane masks out lighting to create an "emissive" effect, ie for glowing lights in otherwise dark areas.
LIGHT_MASK_PLANE	Masks the lighting plane with turfs, so we never light up the void Failing that, masks emissives and the overlay lighting plane
ABOVE_LIGHTING_PLANE	Things that should render ignoring lighting
PIPECRAWL_IMAGES_PLANE	---------------- MISC ----------------------- Pipecrawling images
CAMERA_STATIC_PLANE	AI Camera Static
HIGH_GAME_PLANE	Anything that wants to be part of the game plane, but also wants to draw above literally everything else
RUNECHAT_PLANE	--------------- FULLSCREEN RUNECHAT BUBBLES ------------ Popup Chat Messages
BALLOON_CHAT_PLANE	Plane for balloon text (text that fades up)
SPLASHSCREEN_PLANE	Plane of the "splash" icon used that shows on the lobby screen
ESCAPE_MENU_PLANE	Plane related to the menu when pressing Escape. Needed so that we can apply a blur effect to EVERYTHING, and guarantee we are above all UI.
PLANE_RANGE	The range unique planes can be in
CATWALK_LAYER	catwalk overlay of /turf/open/floor/plating/catwalk_floor
LIGHTING_MASK_LAYER	Typically overlays, that "hide" portions of the turf underlay layer I'm allotting 100 z levels before this breaks. That'll never happen --Lemon
LIGHTING_PRIMARY_LAYER	Misc things that draw on the turf lighting plane Space, solar beams, etc
LIGHTING_ABOVE_ALL	Stuff that needs to draw above everything else on this plane
EMISSIVE_LAYER_UNBLOCKABLE	The layer you should use if you really don't want an emissive overlay to be blocked.
FLASH_LAYER	--------------- FULLSCREEN IMAGES ------------
TYPING_LAYER	--------------- FULLSCREEN RUNECHAT BUBBLES ------------ Bubble for typing indicators
RADIAL_CONTENT_LAYER	1000 is an unimportant number, it's just to normalize copied layers
SCREENTIP_LAYER	Layer for screentips
TUTORIAL_INSTRUCTIONS_LAYER	Layer for tutorial instructions
CINEMATIC_LAYER	cinematics are "below" the splash screen
PLANE_MASTERS_GAME	Plane master controller keys
PLANE_CRITICAL_DISPLAY	This plane master will not go away if its layer is culled. useful for preserving effects
PLANE_CRITICAL_NO_RELAY	This plane master will temporarially remove relays to all other planes Allows us to retain the effects of a plane while cutting off the changes it makes
PLANE_CRITICAL_CUT_RENDER	We assume this plane master has a render target starting with *, it'll be removed, forcing it to render in place
MULTIZ_PERFORMANCE_DISABLE	A value of /datum/preference/numeric/multiz_performance that disables the option
MAX_EXPECTED_Z_DEPTH	We expect at most 3 layers of multiz Increment this define if you make a huge map. We unit test for it too just to make it easy for you If you modify this, you'll need to modify the tsx file too
