+ Baseclass for all grouping 3D primitives
+
+ The description/functionality is identical with the 2D case in groupprimitive2d.hxx,
+ please see there for detailed information.
+
+ Current Basic 3D StatePrimitives are:
+
+ - ModifiedColorPrimitive3D (for a stack of color modifications)
+ - ShadowPrimitive3D (for 3D objects with shadow; this is a special case
+ since the shadow of a 3D primitive is a 2D primitive set)
+ - TexturePrimitive3D (with the following variations)
+ - GradientTexturePrimitive3D (for 3D gradient fill)
+ - BitmapTexturePrimitive3D (for 3D Bitmap fill)
+ - TransparenceTexturePrimitive3D (for 3D transparence)
+ - HatchTexturePrimitive3D (for 3D hatch fill)
+ - TransformPrimitive3D (for a transformation stack)
