<H4>Sampling Rectangles</H4>
When the user is performing the ``Colour Matching'' step of radiometric
correction, it is necessary to display a sampling region subrectangle
in the uncorrected and georeferenced overview windows.  This control
may be used to change to colour of the displayed rectangles from their
default of red.  It is not possible to disable the display of the
sampling rectangles, though they will disappear when the ``Colour
Matching'' step is exited.
