[PD] More than one gem_state outlet

Hello list,

I made a pix_fft2 object that calculates the magnitude of the spectrum [1]
based on [2] and [3]. So far, it works pretty much the same as
pix_opencv_dft but I want to expand this further:

I'm making a different one, and I have problems because I want to output
real an imaginary values as images. The code is in [4].

I'm following these instructions [5], but I can't wrap my head around it.

How would I go about sending a second gem_state (or image) via a 2nd outlet
? Are there any examples out there? What's wrong with [4]?

A solution for this was to output all pixels as a list, but I don't think
it's very efficient and it messes around with the pixel order.
