//! Used by MaskGraphicsScene to embed the ColorMap.
//!
//! A QGraphicsProxyWidget embeds a QWidget-based widget into a QGraphicsScene.
//!
//! The hierarchy MaskGraphicsScene > MaskGraphicsProxy > ColorMap is constructed
//! by calls of QGraphicsProxyWidget functions setParent and setWidget.
//!
//! In zooming mode, mouse events are send to the ColorMap widget.
//! In non-zooming mode, they are ignored (so that they can be processed elsewhere).
