Detailed Description

Handles zoom operations for Isis qt apps.

Author
????-??-?? Jeff Anderson - ???
History:

2007-03-21 Tracie Sucharski - Added zoomFitWidth and zoomFitHeight slots and changed the zoomFit button to contain a popup menu for "Fit to Width" & "Fit to Height".

2008-05-23 Noah Hilt - Added RubberBandTool functionality and changed the mouseButtonReleased Method.

2009-02-12 Steven Lambright - Fixed zooming in/out with rectangle rubber band

2010-06-26 Eric Hyer - Now uses MdiCubeViewport instead of CubeViewport. Fixed some include issues.

2010-07-12 Jeannie Walldren - Created setScale() methods to display a QMessageBox if a scale value could not be set.

2010-07-14 Jeannie Walldren - Fixed bug that caused 1:1 to fail. Added iExceptions if value is manually entered in text box is invalid. Updated documentation.

2010-12-22 Eric Hyer - Removed mouseButtonPress method.

2011-09-28 Steven Lambright - Removed p_userCursor. It was only causing bugs. As a result, the mouseButtonRelease method did nothing so I removed that too. Zooming happens on the rubberBandComplete slot.
