2021-05-09	wrap cuda.memcpy_htod args in np.asarray	mastbaum
	Fixes "TypeError: 'numpy.int64' does not have the buffer interface" error.
2021-05-09	Do not automatically initialize pycuda before forking the camera process.	Stan Seibert
	This causes weird segfaults on Macs, and is probably a source of random crashing on other processes. Also call pygame.init() explicitly in the new process for good measure.
2021-05-09	Put triangles and vertices back onto the GPU if there is sufficient room.	Stan Seibert
	This is an optimization that is helpful for smaller detectors, even if giant water Cherenkov detectors cannot take advantage of it. Modified Mapped() helper function to pass through GPU arrays, which makes it much easier to flip between arrays on the CPU and the GPU.
2021-05-09	Import memoize decorator directly from pytools as it is not present in the ↵	Stan Seibert
	old location in newer pycuda releases.
2021-05-09	Simple BVH generator using new infrastructure	Stan Seibert

2021-05-09	Improve identification of CUDA vector types in struct builder	Stan Seibert

2021-05-09	Allow make_gpu_struct to pack structs containing the CUDA vector types.	Stan Seibert

2011-10-05	Epic port of Chroma from units of meters/seconds/MeV to	Stan Seibert
	millimeters/nanoseconds/MeV in order to match GEANT4, and also avoid huge discrepancies in magnitude caused by values like 10e-9 sec. Along the way, cleaned up a few things: * Switch the PI and SPEED_OF_LIGHT constants from double to single precision. This avoid some unnecessary double precision calculations in the GPU code. * Fixed a silly problem in the definition of the spherical spiral. Now the demo detector looks totally awesome. Also wrapped it in a black surface. Demo detector now has 10055 PMTs. * Updated the test_ray_intersection data file to reflect the new units. * Fix a missing import in chroma.gpu.tools
2011-09-17	Split up chroma.gpu into separate modules. chroma.gpu.__init__ imports ↵	Stan Seibert
	everything from the sub modules, so usage is the same.
