allout-widgets-icons-cache

allout-widgets-icons-cache is a variable defined in `allout-widgets.el'.
Its value is
nil


Documentation:
Cache allout icon images, as an association list.

`allout-fetch-icon-image' uses this cache transparently, keying
images with lists containing the name of the icon directory (as
found on the `load-path') and the icon name.

Set this variable to `nil' to empty the cache, and have it replenish from the
filesystem.
