Detailed Description

The display controller handles displaying images and histograms.

It has an Active object (since it derives from BaseController) but the work is actually done in Active objects inside CChannelFrame/View and CHistogramFrame/View. I choose this solution because much stuff is dependent on the size of the actual window and the scaling is better with one worker thread per window. The DisplayController now merely keeps track of which windows exist and transfers pointer to the current image to these.
