Is it possible to add a stroke/outline to a symbol?
I am doing some character animation (for example a "walk cycle" symbol), and am looking to create a thicker outline around the symbol. I can't just draw the objects inside the symbol with a thicker stroke, as the outline only needs to be thicker when objects are outside the character.
For example, normally the character's arm would have a thick outline, but as it moves in front of the body the outline becomes thinner.
If you've seen the cartoon "Billy & Mandy" you know what i'm talking about:
