36b2fba5b7 De-boxed many uses of Hit and Material. 
Use of generic parameter directly where possible in structures instead
of Box'd values.
Added Material implementations for Box<Material> and Arc<Material> to
aid in the automatic conversion when necessary to use a Sized value for
Material.
Implement From trait for [f32;3] to Vec3 to make some APIs Into<Vec3>
which is a bit nicer to use.
