2017-02-14	ray: add highlight exponent to ray_surface_t	Vito Caputo
	Was a constant at 20, this allows it to be specified per-object.
2017-02-12	ray: tweak surface properties	Vito Caputo
	Make spheres a little more diverse in terms of specular/diffusion, and minor tweak to the plane color.
2017-02-12	ray: update copyright years	Vito Caputo

2017-02-12	ray: improve camera movement	Vito Caputo
	Make the camera orbit around the origin at a varying radius, with kept aimed facing the origin, with some vertical sweep+tilt thrown in.
2017-02-12	ray: fixup ray_object_plane_intersects_ray() bug	Vito Caputo
	We should only consider dot products > 0 as intersected, or >= something very close to 0 (epsilon). As-is resulted in planes moving with camera movement along the plane normal axis. Also fixes plane distance to be non-negative in the current scene.
2017-02-10	ray: implement all orders in ray_euler_basis()	Vito Caputo
	Originally I only implemented pitch->yaw->roll, and being new to all this didn't fully appreciate the limitation that resulted in. This adds all six permutations of pitch/yaw/roll, the scene must specify the desired order when setting up the camera with the euler angles, see the enum in ray_euler.h.
2017-01-18	*: move source into src/ subdir	Vito Caputo
	Restoring some organizational sanity since adopting autotools.
