Hello,
how is it possible to flip upside down an image in glsl example 05.multitexture
I tried to implement this in fragment program:

but it doesn't work. The only thing I can do is changing texture scale and position, but I couldn't do it with negative values like it would be done in pix_coordinates.
In fact when I use pix_multiimage before pix_texture, the image gets flipped, I don't know why...
