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_PLANE	This plane masks out lighting to create an "emissive" effect, ie for glowing lights in otherwise dark areas.
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. only render plate planes should be above this
PLANE_RANGE	The range unique planes can be in
CATWALK_LAYER	catwalk overlay of /turf/open/floor/plating/catwalk_floor
EMISSIVE_RENDER_TARGET	The render target used by the emissive layer.
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
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_EMPTY_RELAY	This plane master will temporarially remove relays to non critical planes if it's layer is culled (and it's critical) This is VERY hacky, but needed to ensure that some instances of BLEND_MULITPLY work as expected (fuck you god damn parallax) It also implies that the critical plane has a *'d render target, making it mask itself
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
