 Hello everyone,

  Simple question, I think. I would like to obtain the RGB color value
of any place I point to within the perfly scene. I can get the current mouse
pointer position, next I would like to be able to press a key to extract
the color value that I am pointing to. I can do this with a snoop
program, but I would like to be able to just point and 'click' and write
the color values along with other parameters to a file.

  The purpose of this is to 'calibrate' Performer's fog density function
to the meteorological fog visibility model. Thanks.
