Querying "pixels" just didn't do anything visible with an

tried for that argument. Maybe I read the docs not well enough..
set extracted_pixels [$wand GetPixels 10 5 80 10 "RGB" char]
This was the key...
Seeing "GetPixels" at work got me trying again...
I now just load the original pic into (GraphicsMagick-powered)
TclMagick0.46 and use GetPixels for the rectangles I need to
examine...
and it became like *5 times faster* than my previous approach
with calling "convert" and parsing it's output. :-)
