Convex hull gap

[frca]

For convex hulls, cylinders and cones, the
margin is added to the extents of the object, so a gap will occur, unless you adjust the graphics mesh
or collision size. For convex hull objects, there is a method to remove the gap introduced by the
margin, by shrinking the object. See the Demos/BspDemo for this advanced use.

I haven't found mentioned method shrinking the hull in the demo's sources. Could someone please provide the actual line from the sources doing it so I can find it easier?
Thanks.
