-Attempt to fix several OpenCL build errors that were occurring on Mac. --Code changes -Improve the coloring code during final accum by getting rid of the last remnants of unnecessary scaling to 255 from flam3. -Begin work of supporting 16bpc on the GPU.

/// This supports multi-GPU rendering and is done in the following manner:

|
/// -When rendering a single image, the iterations will be split between devices in sub batches.
|
|
/// -When animating, a renderer for each device will be created by the calling code,

|
/// and the frames will each be rendered by a single device as available.

/// The synchronization across devices is done through a single atomic counter.
