-// The difference between this and Transfrm.h is that Transfrm copies the data.
-//
-// It assumes the filter has one input and one output stream, and has no
-// interest in memory management, interface negotiation or anything else.
-//
-// Derive your class from this, and supply Transform and the media type/format
-// negotiation functions. Implement that class, compile and link and
-// you're done.
