Bitmap filter base class.
Library: xviews or winviews or mviews (mutually exclusive)
The bitmap filter lets you manipulate bitmap data. This class provides general attribute management and must be subclassed. Each filter exposes its input and output bitmap data using names. The class IlvFilterFlow
manages a list of filters and a list of bitmap data items.
