             *     Windows 95/98/Me: When the biCompression member is
             *     BI_BITFIELDS, the system supports only the following
             *     16bpp color masks: A 5-5-5 16-bit image, where the blue
             *     mask is 0x001F, the green mask is 0x03E0, and the red mask
             *     is 0x7C00; and a 5-6-5 16-bit image, where the blue mask
             *     is 0x001F, the green mask is 0x07E0, and the red mask is
