PictureViewer is a Controller that manages a window which displays a picture. It concerns itself with which picture from the Naviator Context should be displayed. It provides navigation control over the collection as well as mouse and keyboard control over the zooming.

The user can zoom in on a picture coordinate by clicking the left mouse button. The middle button scales the picture so that it fits in the available space and centers it there. The right mouse button zooms out.
