The main loop only handles transparent intersections from the camera ray. Therefore we can simplify some things. * Avoid PATH_RAY_CAMERA check, this is always true. * Avoid path_state_next() call, we can just set transparent flag and increase transparent bounces. This way we avoid the function call and some branching. Also remove debug num_ray_bounces++, this is incorrect here as no indirect bounce happens here. Should be no functional changes.
