That's not doable =/. I have to put the swf on adobe premiere to add decent audio and a bunch of other stuff that needs video editing. Premiere doesn't seem to read code as i saw some time ago trying to upload an animation in which i used 3d manipulation tools.
Also, increasing the size of a symbol that contains a very small line oftenly makes the line look awkard (but not as awkard when the line is medium-sized).
