Please share your widgets on Cuis-Smalltalk-UI for re usability within 
the cuis community.

In this repo, there is a simple icon importer for both png and SVG. The 
icons are rendered on Form and cached on a dictionary to improve speed. 
When you have a lot of vectorial icons on a GUI, you may have slowdown 
if they are repeatedly rendered from the vectorial forms. I noticed that 
with the DrGeo circular toolbar.

The icon importer could be extend to support this compact format
