  22  * These interface descriptions are supposed to be used for automatic proxy
  23  * generation by an IDL compiler.
  24  *
  25  * While it's possible to convert include/vfw.h to an .idl, that's proved to
  26  * be a major waste of an effort because the resulting interface descriptions
  27  * can't be used for automatic proxy generation since they are not compatible
  28  * with IDL compiler restrictions for proxies, and fixing them up would make
  29  * generated vfw.h source incompatible with PSDK's equivalent.
