Would handling Icons via output port be totally insane?
The icon would be fully contained in the plugin. Whether or not 
restrictions on must/should/do not use of image formats is a question, 
it could be as simple as an rgba block of pixel data. Whether or not the 
data is dynamically created (eg. drawn to match a size) or from static 
resource would be left open.
