AcquireWindowAggregateClipShape
The AcquireWindowAggregateClipShape method calculates and returns a reference to a shape object that represents the window aggregate clip shape of this facet.
ODShape AcquireWindowAggregateClipShape (
                                 in ODCanvas biasCanvas);
biasCanvas
kODNULL if the geometry is in platform-normal coordinates, otherwise a reference to the canvas object to whose coordinate space the geometry is biased.
return value
A reference to a shape object that represents the window aggregate clip shape.

DISCUSSION
The window aggregate clip shape describes this facet's clip shape on its window. The window aggregate clip shape is calculated by intersecting the clip shape of this facet with the clip shapes of all containing facets displayed on this facet's window canvas.
This method increments the reference count of the returned shape object. When you have finished using that shape object, you should call its Release method.
