Oh no! I was thinking of the dt_iop_clip_and_zoom_demosaic_{half,third}_*() 
functions in imageop_math.c. Those don't have OpenCL implementations, though? 
Certainly getting into revising OpenCL code would be a way more invasive effort.

I also remember now that I wanted to look into whether taking advantage of box 
filters being separable would speed up the code. But that would involve 
allocating a bit of memory so might also be something about which to be 
conservative.
