I use the filepath of the requested item to derive a cache file name in
the user's xdg cachedirectory. I also add a way to update items in the
cache if we detect that the mtime has changed, and support loading items
from the cache if the source file has been deleted.

The Texture Cache will be used to map filenames to Gdk.Textures loaded
into memory. The application can then re-use textures instead of making
expensive filesystem calls and loading the same images multiple times.
