With draw or if I use ggee/image the data would come from the output of 
[pix_write]

but if I want to display on the fly I use pix_snap and pix_dump for an 
animation file, or pix_dump only for a texture file.

I'd be glad to be able to do this, the same thing should be possible to 
do with the Gem multiple windows options, but I'm not sure I'd try last 
Gem yet on my windows machine and that would imply the writing of all 
the bindings for drawing the interface in gemwin...

Since it's a preview image for making a shortcut, it doesn't need many 
pixels, so the RGB values from pix_dump are converted to a message that 
would generate the image on the interface, stored into a datastructure 
through a text object. That's not very fast compared to a process using 
hardware acceleration but works smoothly with 64x64 images.
