 *   Draw a window frame inside the given rectangle, and update the rectangle.
 *
 *   Bugs
 *        Many.  First, just what IS a frame in Win95?  Note that the 3D look
 *        on the outer edge is handled by NC_DoNCPaint95.  As is the inner
 *        edge.  The inner rectangle just inside the frame is handled by the
 *        Caption code.
 *
 *        In short, for most people, this function should be a nop (unless
 *        you LIKE thick borders in Win95/NT4.0 -- I've been working with
 *        them lately, but just to get this code right).  Even so, it doesn't
 *        appear to be so.  It's being worked on...
