// Mutable appearances are an inbuilt byond datastructure. Read the documentation on them by hitting F1 in DM.

// Basically use them instead of images for overlays/underlays and when changing an object's appearance if you're doing so with any regularity.
|
|
// Unless you need the overlay/underlay to have a different direction than the base object. Then you have to use an image due to a bug.
|

|
|
// Mutable appearances erase template vars on new, because they accept an appearance to copy as an arg
|
|
// If we have nothin to copy, we set the float plane
