Detailed Description

Viewport for Isis Chips.

Author: 2007-05-01 Tracie Sucharski

History:: 2008-09-09 Tracie Sucharski - Added setCircle and setCircleSize methods.

History:: 2010-06-16 Jeannie Walldren - Modified geomChip(), nogeomChip(), rotateChip() and reloadChip() to catch possible iExceptions from Chip's Load() method and display Error in QMessageBox

History:: 2010-11-17 Eric Hyer - Added cubeToViewport method and setControlNet slot. paintEvent can now use the control net to paint measures in the viewport.

History:: 2010-11-22 Eric Hyer - ChipViewports can now be stretched by stretching CubeViewports opened to the same cube

History:: 2010-11-24 Eric Hyer - Fixed bug where crosses were painted one screen pixel off on each direction. Also no longer paint cross under the large main red crosses.

History:: 2010-12-01 Eric Hyer - Added stretch locking

History:: 2011-06-07 Debbie A. Cook and Tracie Sucharski - Changed point type "Ground" to "Fixed".

History:: 2011-06-14 Tracie Sucharski - Added mouseClick signal. Qnet needed to know if user moved the tackpoint vs. simply loading a new chip, or geoming the chip.

History:: 2011-06-15 Tracie Sucharski - Changed signal mouseClick to userMovedTackPoint. TODO: Could not use tackPointChanged signal because that signal is emitted whenever the measure is loaded not just when the user initiates the move. This should be cleaned up.

History:: 2011-09-14 Tracie Sucharski - Added user option to determine whether control points are drawn.

History:: 2012-07-26 Tracie Sucharski - Added method to return zoom factor and slot to zoom to a specific zoom factor.
