1133 * Bugs
1134 * Many. First, just what IS a frame in Win95? Note that the 3D look
1135 * on the outer edge is handled by NC_DoNCPaint95. As is the inner
1136 * edge. The inner rectangle just inside the frame is handled by the
1137 * Caption code.
1138 *
1139 * In short, for most people, this function should be a nop (unless
1140 * you LIKE thick borders in Win95/NT4.0 -- I've been working with
1141 * them lately, but just to get this code right). Even so, it doesn't
1142 * appear to be so. It's being worked on...
