When calling the process method several time without drawing, we don't
need to release the GL objects or even calling clFinish. So here we
internally keep track and only do the 'finishing up' of the CL process
when doing a drawing call.

- It's not longer hardcoded / computed in the kernel, but computed
once and read from constant memory
- By default it uses a periodic Hamming window
- But you can load any window as a simple array of float
- Different types of window is deemed out-of-scope here. The default
is provided just for convenience to have something valid.

Originally I wanted the CL/GL part to be as separate as possible and
have no shared data. But it's too inconvenient since a beside the
CL / GL objects there is also configuration data that should be shared
and distributed between the two.
So instead we still have separate gl/cl state that are restricted but
the function act on a shared 'struct fosphor' object that contains
everything that's shared and exposed to both cl.c and gl.c
