Shadows now working, though they are still voxel based. Need to calculate where on the surface the ray hits, and then send the ray out from that point.

various tweaking and figuring on the octree. The weird hybrid dfs bfs thing they have going will be annoying to do in one pass. Might defer it out to two passes. First building the octree, second culling and passing the octree to the gpu

MBP was having problems with out of bounds memory operations with the way the cam dir was handled. sf::vector3f -> float3 and while accessign the Zth element. I'm assuming it was because of some weird backend stuff regarding that gentypeOdds are actually gentypeOdds + 1. Converted write_imagef's to write_imageui's though I don't think that really helps anything. Fixed the bottom half of the screen getting cut off. View matrix import error. Fixed problem the MBP had with negative values during device init, that was a weird one.

WORKING! Awesome! It now casts fully inside the gpu,

context is then switched to gl and then rendered via sfml.
It has no loop, no controls, and the aspect ratio is off,

Added args and buffer handling, but now clEnqueueNDRangeKernel is failing

Switched names, thinking about how to do kernel args, and buffers.

Need to do a bit more reading on how to set up interop.
Also need to figure out the buffer thing for regular primative buffers, and also image buffers

Large amount done. OpenCL is almost completely abstracted out to the class
...
from init to kernel compilation. Next will be getting buffer handling, executing, and reading done.
Changed the kernel to a more minimal example.
Added a jump table for error codes and an assert function for error checking.
Added a routine to compare all the available cl devices and platforms, chooses the high clock of either the GPU or CPU.
