Notes
Notes: This routine makes it easier to insert an embedded
smaller image into a displayed image. The image should
be ready for display in the non-transparent areas. The
transparent value may be out of that range. For 24-bit
color images give the 24-bit color value that is
transparent. Works on the current window.
