| Issue 19: | Offload fractal rendering to the GPU, with OpenCL | |

I am making exploratory ventures into this. It might not pan out. Most GPUs should be able to do 32-bit integer and float computation, and some will do 64-bit. I don't know what mine will do. Starting with http://www.browndeertechnology.com/coprthr_stdcl.htm. The windows package is for 64-bit only, whereas my MSVC is for 32-bit only, so I'm adapting and recompiling it. Still have not got anything compiled and running yet. I have not yet thought about how the Mandelbrot computations can be translated into OpenCL style. I don't think the standard mfunc interface will work. So a variation on the STANDARD drawing mode that bypasses mfuncs and instead passes larger chunks of the work to OpenCL will probably be in order. One possibility is to make it like PARALLEL mode: distribute pixels to workers in even steps, so that all workers are likely to have similar shares of expensive pixels.
