Note that the camera maintains camera-space-to-world space transform matrix `iview` that you will need to use in order to get the new ray back into **world space**. Note that since `iview` is a transform matrix, it contains translation, rotation, and scale factors. Be careful in how you use it on specific objects, and take a look at `lib/mat4.h` to see what functions are available for the `Mat4` object.

Once you have implemented `Pathtracer::trace_pixel`, `Rect::sample` and `Camera::generate_ray`ou should now have a camera that can shoot rays into the scene!
