Re: "the upcoming OpenCL target"

Exactly, Vulkan is meant to replace both OpenGL _and_ OpenCL, in a single 
language. I suspect, in many case, someone using OpenGL is likely to use OpenCL 
(or CUDA) too. And they need to learn two different languages to do that. 
Vulkan will make the life of such devs easier (in theory).
