[PD] [Gem] Modifying single pixel of pix image

Is it possible to manipulate a single pixel of a an image loaded by
[pix_image]? Specifically, I'd like to change the alpha value of
certain pixels. It doesn't matter to me whether the manipulation
happens in the pix realm or the GL realm. Currently I can think only of
cumbersome ways like using [pix_dump] -> [pix_set] and applying the
manipulation to the largish list passed between them. Or by using
[pix_pix2sig~] -> [pix_sig2pix~] which is basically the same, but would
allow to do the manipulation on a table.
