I have already added the mono-mixer to the workshop directory under operations,
I think we want a bit more functionality similar to the one already
existing in GIMP as well,
for instance making sure the values always add up to 1.0 to maintain
the range in the image
before moving it to the color directory where it properly will belong.
Speaking of color to gray scale, be sure to test the c2g operation
also in the workshop.
I am going to look into adding the other files as well, similarly I'll
add the operation to the workshop dir first.
