| /** ShadowPrimitive2D class |
| |
| This primitive defines a generic shadow geometry construction |
| for 2D objects. It decomposes to a TransformPrimitive2D embedded |
| into a ModifiedColorPrimitive2D. |
| |
| It's for primtive usage convenience, so that not everyone has |
| to implement the generic shadow construction by himself. |
| |
| The same geometry as sequence of primitives is used as geometry and |
| as shadow. Since these are RefCounted Uno-Api objects, no extra objects |
| are needed for the shadow itself; all the local decompositions of the |
| original geometry can be reused from the renderer for shadow visualisation. |
