Detailed Description

The MaskContainerView is nothing move than just transparent rectangle to cover axes area of ColorMapPlot inside MaskGraphicsScene.

The goal of this rectangle is to hide all MaskViews if they are going outside of ColorMapPlot.

The size of the rectangle always matches axes viewport at any zoom level. All MasksViews are added to MaskContainerView as children.
