Vars
assigned_oranges_ear	what /mob/oranges_ear instance is already assigned to us as there should only ever be one. used for guaranteeing there is only one oranges_ear per turf when assigned, speeds up view() iteration
directional_opacity	List of light sources affecting this turf. Which directions does this turf block the vision of, taking into account both the turf's opacity and the movable opacity_sources.
dynamic_lumcount	Lumcount added by sources other than lighting datum objects, such as the overlay lighting component.
fixed_underlay	Icon-smoothing variable to map a diagonal wall corner with a fixed underlay.
hard_armor	Flat-damage-reduction-based armor.
hybrid_lights_affecting	hybrid lights affecting this turf
lighting_corner_NE	Lighting Corner datums.
opacity_sources	Lazylist of movable atoms providing opacity sources.
soft_armor	%-reduction-based armor.
turf_flags	Turf bitflags, see code/__DEFINES/flags.dm
Procs
ScrapeAway	Take off the top layer turf and replace it with the next baseturf down
add_opacity_source	Proc to add movable sources of opacity on the turf and let it handle lighting code.
can_teleport_here	Are we able to teleport to this turf using in game teleport mechanics
check_alien_construction	Check if alien abilities can construct structure on the turf Return TRUE if allowed, FALSE otherwise
check_disallow_alien_fortification	Checks for whether we can build advanced xeno structures here Returns TRUE if present, FALSE otherwise
clear_signal_refs	WARNING WARNING Turfs DO NOT lose their signals when they get replaced, REMEMBER THIS It's possible because turfs are fucked, and if you have one in a list and it's replaced with another one, the list ref points to the new turf We do it because moving signals over was needlessly expensive, and bloated a very commonly used bit of code
fromShuttleMove	Base procs
get_submerge_depth	Returns the number that shows how far an AM is offset when submerged in this turf
get_submerge_height	Returns the number that represents how submerged an AM is by a turf and its contents
on_change_area	Allows for reactions to an area change without inherently requiring change_area() be called (I hate maploading)
recalculate_directional_opacity	Calculate on which directions this turfs block view.
reconsider_lights	Causes any affecting light sources to be queued for a visibility update, for example a door got opened.
remove_opacity_source	Proc to remove movable sources of opacity on the turf and let it handle lighting code.
static_lighting_build_overlay	Builds a lighting object for us, but only if our area is dynamic.
transfer_area_lighting	Transfer the lighting of one area to another
wash	cleans any cleanable decals from the turf
zFall	Precipitates a movable (plus whatever buckled to it) to lower z levels if possible and then calls zImpact()
zImpact	Called each time the target falls down a z level possibly making their trajectory come to a halt. see __DEFINES/movement.dm.
zPassIn	If we'd allow anything to travel into us
zPassOut	If we'd allow anything to travel out of us
