//	FILTER EXEMPTION:
//
//	As a special exemption to the GPL in order to permit creation of
//	filters that work with multiple programs as well as VirtualDub,
//	compiling with this header file shall not be considered creation
//	of a derived work; that is, the act of compiling with this header
//	file does not require your source code or the resulting module
//	to be released in source code form or under a GPL-compatible
//	license according to parts (2) and (3) of the GPL.  A filter built
//	using this header file may thus be licensed or dual-licensed so
//	that it may be used with VirtualDub as well as an alternative
//	product whose license is incompatible with the GPL.
//
//	Nothing in this exemption shall be construed as applying to
//	VirtualDub itself -- that is, this exemption does not give you
//	permission to use parts of VirtualDub's source besides this
//	header file, or to dynamically link with VirtualDub as part
//	of the filter load process, in a fashion not permitted by the
//	GPL.
