[FEATURE] Treat Icons the same as image paths

[LurkAndLoiter]

Description of the requested feature

regarding issue 1266 where lacking variance in icon sizes can result in irregular icon size outputs. This does not seem to be the case when we use hard links and then use the image-{width,height} properties.

Is there any reason we could not treat the icons the same as image hardlinks when we include a image-{width,height} property or even just in general use? I'm unaware of any underlying trade offs to this approach so forgive my naivety if there is some.

Proposed configuration syntax
