AcquireWindowFrameTransform
The AcquireWindowFrameTransform method calculates and returns a reference to a transform object that represents the window-frame transform of this facet.
ODTransform AcquireWindowFrameTransform (
                                 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 transform object that represents the window-frame transform.

DISCUSSION
The window-frame transform describes the frame coordinate space of this facet on its window. The window-frame transform is calculated by concatenating this facet's external transform with the internal and external transforms of all containing facets displayed on this facet's window canvas.
This method increments the reference count of the returned transform object. When you have finished using that transform object, you should call its Release method.
