    Re: CLH_ERROR_NO_BINARY_FOR_GPU for image2d_t

    Here is what Apple had to say about this issue. Apparently they are looking to Khronos to update the spec. They effectively say that image2d_t and image3d_t (as well as sampler) are structures, and...

    __write_only __global image2d_t newImg,
    __constant uint *filter, const int...
