Most icon themes have a set of different sized icons that will be used for the same thing but change depending on the size of the icon being viewed. In nemo, if I want to change the icon of a file or folder, I can just go to properties, click on the icon, and choose a new icon. However, nemo will use the same icon file no matter what the size of the icon is, whether you use list view, icons view, compact, etc.
How do I change the icon on a file or folder and make it so that nemo will use the proper sized icon depending on the current view (ie 16x16 png for list view, scalable svg for icons view, etc.)?
