+/* QDesignerDialog / QDesignerWidget are used to paint a grid on QDialog and QWidget main containers
+ * and container extension pages.
+ * The paint routines work as follows:
+ * We need to clean the background here (to make the parent grid disappear in case we are a container page
+ * and to make palette background settings take effect),
+ * which would normally break style sheets with background settings.
+ * So, we manually make the style paint after cleaning. On top comes the grid
+ * In addition, this code works around
+ * the QStyleSheetStyle setting Qt::WA_StyledBackground to false for subclasses of QWidget.
