[GEM-dev] pix_set new features

[Antoine Villeret]

and what about the opposite ?
stay in discrete coordinate in the code and add a normalized message ?
in that way the conversion is done only once (when the ROI is set in
normalized coord) and not each time we set the data (for pix_set)
maybe i'm going wrong...
