2011-07-30	when throwing photons from the light source out onto the scene, photons are ↵	Anthony LaTorre
	now thrown randomly across each triangle instead of only at the center of each triangle. all of the rendering kernels have been rewritten so that they operate additively; for example, you may now throw photons from the light source onto the scene, render from the camera to the scene, then throw more photons and render again.
2011-07-21	pull random number generator states out of the photon struct; this allows ↵	Anthony LaTorre
	you to copy photon information within a thread but still keep a single random number generator throughout the thread.
2011-07-21	hybrid monte carlo render now distinguishes between the two different sides ↵	Anthony LaTorre
	of each triangle. reduced the number of runs to average when propagating photons from each pixel in render.py from 5 to 1; the speed improvement outweighs any small improvement in the quality of the rendered image.
2011-07-20	in the previous commit i wrongly edited the code to reflect/transmit across ↵	Anthony LaTorre
	a boundary
2011-07-20	pulled a lot of the photon propagation code out of src/kernel.cu into ↵	Anthony LaTorre
	src/photon.h so that photon propagation by propagate() in kernel.cu and the hybrid monte carlo ray tracing use the same code. instead of a single state, photons now carry the history of the processes they've undergone. this history is stored as a bitmask; see src/photon.h. start_node and first_node of the mesh are now stored as global variables in mesh.h instead of being passed to kernel functions.
