update_icons() uses animate() and transforms to actually turn the sprite rather than needing them pre-turned. Mobs that lie down do so with an animation rather than appearing on their side. You can lie down facing THE LEFT OH SHIT.

Cloakers still don't work well. The fix is probably just finding a proc that runs on equip/uequip/when bagged/when dropped. Fuck that. Ninjas work. Things that are cloaked fade to the cloaked alpha, it's pretty cool.

The "lying down" icon_states for everything you could equip are all now unnecessary. They aren't removed yet though.

The dmi changes are to make xenos all face upward so when they turn, they're lying down rather than facing south and looking like they're doing a handstand. They're not terribly good when facing the wrong way. I expect WJohnson to have a fix for this by New Year's.

Comments aren't changed. The overlays_standing list is still around because overlays is not a normal list, and BYOND's normal list functions are worth the extra cost of keeping a spare list of images.
Give mob/living a cloak_stacks list. If there's anything in this list, cloak the mob upon the next update_transform().

Give all mob/living/carbon a shared update_transform(). Larva have their own because they're special.
Update to master (branch was way out of date)
Redo on that merge into master, my bad.
Wow RobRichards thanks for making Jenkins cry
Increased speed of animate calls to 2.
Added a pixel_y component to better align laying down with current laying down and look more like lying on the floor rather than floating in the air.
Lock aliens lying to 90 degrees.
Make them use the sleep sprites when unconscious.

Lock mobs laying down to either NORTH or SOUTH.

No more cloakers, no more cloak_stacks. Also removed that silly "I'll make an icon and then make an image of that icon" bullshit.
Merge pull request #2387 from MrPerson/Animation_OLD

Mobs use animate() to rotate
