/** A theme is a set of properties describing fonts, colors, and bitmaps to be used to draw
    background, pane borders, and view content.

    At the moment the properties can be accessed via the getPropertyValue() method.

    For a resource URL of a pane or a view you get the name of the
    associated PaneStyle or ViewStyle.

    For the name of pane or view style suffixed with and underscore and the
    name of configuration property, and maybe additionally suffixed by
    another underscore and sub property name you get the associated
    property.

    Example: you want to access the top left bitmap of a pane border
        (simplified code):

    String sStyleName = getPropertyValue("private:resource/pane/Presenter/Pane1");
    XBitmap xBitmap = getPropertyValue(sStyleName + "_TopLeftBitmap");

    For the offset of the bitmap you can call
    Point aOffset = getPropertyValue(sStyleName + "_TopLeftOffset");
    
    This is work in progress.
