Errr....... it seems that's not true. I still don't understand how 
texunits work but I've tested the abovementioned approach with 9 
textures and it worked.

However, curiously enough, if I try the following:

[square 4]

and I send [pix_texture] a "textunit N" message, it stops showing the 
image at N=4.

Does anybody know why?
