fade_in_time	Time for the image to fade in.
fade_out_time	Time for the image to fade out and delete itself.
focus	The focus action for adjusting echolocation settings.

image_expiry_time	Time for the image to start fading out.
overlay_states	Typecache of overlay icon states to the typecache of types that get that overlay.
planes	List of planes we apply our filters to.
saved_appearances	All the saved appearances, keyed by icon-icon_state.
Procs
deafness_check	Add or remove SIGHT_BYPASS depending on if we are deaf or not
