Image intensity scale does not seem to change with changes to the min/max visible & cutoff values.
To the left of the exposure image is a set of values to change scaling of the image. There is a checkbox, label and text entry. The Checkbox enables, disables this. The text box sets the value to be used. The image does not seem to change (with wxpython 3.0) when the value in the checkbox is changed. The user can change this value using windows and the Python 27 provided by Chengjun. Toggling the checkbox does get the new value to register.
