+- Skins can now inquire the menu category for which their cSkinDisplayMenu is currently
+  being used. This can be done either through a call to cSkinDisplayMenu::MenuCategory()
+  or by reimplementing cSkinDisplayMenu::SetMenuCategory(). This information allows a
+  skin to use special icons or decorations for the various types of menus in VDR.
