If you need to swap red and blue, you can do that using the GEM equivalent 
of GridFlow's

[#inner (3 3 #
   0 0 1
   0 1 0
   1 0 0)]

which I think is [pix_colormatrix].

If you want to correct for mistaking U and V then you will have to replace 
the ones by other numbers, possibly 15/8 and 8/15.
