/*
 * These interface descriptions are supposed to be used for automatic proxy
 * generation by an IDL compiler.
 *
 * While it's possible to convert include/vfw.h to an .idl, that's proved to
 * be a major waste of an effort because the resulting interface descriptions
 * can't be used for automatic proxy generation since they are not compatible
 * with IDL compiler restrictions for proxies, and fixing them up would make
 * generated vfw.h source incompatible with PSDK's equivalent.
