Detailed Description

This widget encompasses the entire matrixDisplay scene.

This widget is a self-contained view of the correlation matrix resulting from a bundle adjust. It uses Qt's graphics scene/view framework. This widget holds the graphics scene, view, and items. It will also hold the options dialog for the matrix.
