Creates a 2d
histogram of the x and y gradients of the pixels in a rectangular
region of interest (ROI). The number of neighbouring pixels used to
calculate the gradient can be set (from 1 up to half of the smallest
dimension of the ROI). If a ROI is too close to the edge of the image
to calculate a slope over the number of pixels specified, then the ROI
will be reduced in size as necessary. Axes corresponding to zero
gradient can be added to the histogram. Press the option key to bypass
the dialog box.
