/*
 *  This program hacked from the 'DIBLOOK' MFC example, with
 *  the added capability of multi-format viewing besides BMP.
 *  This was a testbed for paintlib under Win32, really,
 *  and we also use the quick DrawDib bitmap engine.
 *  Reuse at will in derived work; just acknowledge their due credit
 *  to the authors of paintlib and the decoding libraries it relies on.
