Filter for sub shapes

[DocAce]

I have a physics body with a compound collision shape and would like to be able to ignore some (transparent) child shapes for certain raycasts (e.g. lens flares, visibility checks). I would prefer to keep everything in a single body.
The child shape already has the required data in a custom DecoratedShape, but the BodyFilter is of course only called to filter entire bodies. Would it be possible (or rather: recommended) to either extend the BodyFilter or to add some kind of SubShapeFilter class?

NarrowPhaseQuery::CastShape / TransformedShape::CastShape already offers the interface to pass a ShapeFilter class to do what you're asking for. I didn't need a shape filter on CastRay/CollidePoint/CollideShape so I never implemented it. I added it for CastRay as well now in #168. Try it out.

Thanks a ton, I will try it asap!
Edit: it works, thanks again :)
