/*! class RGHistoPlotAttrSelect
 *
 *  Widget for histogram plot attributes selection.
 *
 *  Options:
 *  - \b rgHPASGroupLayout:       use group frames instead of lines with labels
 *  - \b rgHPASNoLabel:           no labels
 *  - \b rgHPASHisto2D:           select attributes for 2D histograms (default is 1D)
 *  - \b rgHPASHisto3D:           select attributes for 3D histograms (default is 1D)
 *  - \b rgHPASAngles3D:          display angles widgets for 3D views
 *  - \b rgHPASExpandColorNumber: color widget is expandable, instead of
 *                                fill widget (default)
