Qt 5 to-do in qcolordialog.h

qtbase/src/widgets/dialogs/qcolordialog.h has the following Qt 5 to-do commnet:

    // ### Qt 5: use QColor in signatures
    static int customCount();
    static QRgb customColor(int index);
    static void setCustomColor(int index, QRgb color);
    static void setStandardColor(int index, QRgb color);

If this can be handled without breaking source-compatibility, it should be actioned for Qt 5.0.0. If not, the comment should be removed or changed to a Qt 6 to-do.
