[PD] Gem: color to pix

[Alexandre Quessy]

Hi,

Its been a little while since I am trying to _add_ a color to a pix. Is
there a way to do so ? The thing is that if I put a colored rectangle
over a pix_textured reactangle, it kind of desaturate the picture.

I know such a thing is much easy in Gridflow, but I got to use Gem on
OSX for this time again. If it is the only, though, I might try to
compile Gridflow with its new export_pix and import_pix on OSX...
