I migrated the [GR Mandelbrot example](https://github.com/jheinen/GR.jl/blob/master/examples/mandel_ocl.jl) to OpenCL 0.10 (based on [this](https://github.com/JuliaGPU/OpenCL.jl/blob/master/examples/notebooks/mandelbrot_fractal.ipynb) notebook).  
Unfortunately I could not use the `access` parameter in `CLArray()`. Does this feature require special package versions?

CLArray doesn’t currently expose an `access` parameter from the underlying buffer. I’m not sure if we should add this; SVM buffers support it, but USM buffers don’t AFAICT.
