* Add support for intermediate rendering passes to IconRenderer. Normally,
the whole icon is rendered in a single pass, which means shapes cannot
overlap. With the change, intermediate rendering passes are inserted when
a shape is encountered that contains transparency. This is an easy way to
allow for more feature rich icons, with easy support for glossy/reflective
surface effects or other such effects that require support for transparent
shapes on top of other shapes.
