+/** 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):
+
+    OUString 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.
