Remove the OpenCL Bicubic scaling option. Unfortunatly it's causing too many problems and it's maximum 5% performance improvement (in ideal circumstances) doesn't justify the effort to continue with it. The OpenCL framework will remain in place in case we decide to use it for something in the future. Closes #690
