// Renderer needs to handle the distinction between a few difference circumstances.
// A.) The machine supports OpenCL and cl_khr_gl_sharing
//          Everything is normal, rendering is handled on-gpu
// B.) The machine support Opencl and NOT cl_khr_gl_sharing
//          For every frame we have to pull the screen buffer from the GPU's memory
// C.) The machine does not support OpenCL
//          We must use the fallback software renderer

// Renderer will hold its own CL_Renderer class which contains all of the data
// and functionality that the CL_Wrapper class currently does, but with the
// intent of leaving it specialized to only the raycaster. Any further OpenCL
// work can use its own class
