I've made a 2D light symbol and saved it has an object.
Changed it's subtype to light.
Works fine except I'd like to get rid of (or bring in closer) the outer 
4 bounding points shown in the attachment.
I've searched though the 2D script but don't see any obvious place to
adjust this.
Any hints appreciated.
Thanks
