Plan for layers system in shape_3dedge.
Split out images from the rest of the jigsaw.  Should make the jigsaw much more flexible (different sized images, etc).
Start writing ocl_shim, which I really need (W.I.P.)
Another line to ocl_shim
Get OclShim working, complete with a nice (?!) macro for defining the CL functions I want to import from the DSO.
Complete the use of OpenCL via the DSO and remove -lOpenCL
Always handle errors.  Although, when I use --cl-lib-dir I get weird things right now ......
