graph_pixel (and other histograms): Add the ability to suppress enormous bins. #27

We will want the ability to suppress (i.e., not display) histogram bins that overwhelm the plot.
Here is an example using graph_pixel. I am trying to display the pixel distribution in the overscan regions, but don't want to select a region that contains only overscan pixels. (There may be use cases where optimal region selection is not possible.) The overflow bin overwhelms the rest of the histogram, which actually has a peak near 100.

Can we use log option to overcome this? Or do we set a threshold on bin counts of overflow/underflow (for example, 10 times of peak value)?

This is what I have if using log option.

This is a partial fix, however the user may want to view the interesting part of the plot in linear mode. Linear plots show some subtle details that are not visible in log plots.
