/**
 * This is the Controller class of the software component TextureObject. This
 * component is responsible for rendering cv::Mats on a disply canvas. Other
 * components can trigger the SLOT receiveCvMat(std::shard_ptr<cv::Mat> mat,
 * QString name) in order to render their images. Usually this would be the
 * component MediaPlayer which will send the original cv::Mat from an
 * ImageStream to controller class ControllerTextureObject. An other component
 * is the BioTracker Plugin. If a cv::Mat is manipulated by a Tracking
 * Algorithm the Plugin is able to send that cv::Mat to this component. The
 * Parameter name will be listed in the combobox widget on the MainWindow
 * widget. The ControllerTextureObject class controlls the of the
 * TrextureObject Component.
