Remarks

The layer affects all drawing until the returned CanvasActiveLayer object is closed. In C# this is typically done with a 'using' statement, or in C++/CX the 'delete' keyword.

Antialising mode of the clip geometry is determined by the value of the Antialiasing property when CreateLayer is called.
