On Windows 9x when you copy a high color bitmap onto the clipboard, it always gets converted to a 24-bit DIB when the CF_DIB format is specified. On Windows XP this conversion doesn't happen. Some applications are only designed to handle 8-bit and 24-bit DIBs. This compatibility fix converts the high-color DIBs to 24-bit DIBs.
