2017-02-12	ray: remove vestigial stdio.h include	Vito Caputo
	Leftover from debugging presumably
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.
2017-02-09	ray: remove redundant recursion depth increment	Vito Caputo
	trace_ray() bumps the depth, the reflection ray trace_ray() call just needs to propagate the depth variable not advance it as well. This was probably vestigial from early development and never got taken out. This does mean more reflections now, and correspondingly slower rendering, but it at least makes MAX_RECURSION_DEPTH accurate. The define can be changed if the performance is too bad.
2017-02-09	ray: fix mistake in ray:sphere intersection math	Vito Caputo

2017-01-18	autotools: s#../../#@top_srcdir@/src#	Vito Caputo
	The relative path broke out-of-tree builds. Previously the following: $ mkdir /tmp/foo $ cd /tmp/foo $ ~/src/rototiller/configure $ make Would fail to compile unable to locate the headers in ~/rototiller/src This fixes it.
2017-01-18	*: move source into src/ subdir	Vito Caputo
	Restoring some organizational sanity since adopting autotools.
