Arguments: pixmap
Tells the operating system to destroy its device-dependent pixmap
resource that it is using for a pixmap object, and sets the
pixmap-handle of the pixmap object to nil. After this is done, the pixmap can still be
used, but will be drawn by sending the array of pixels to the
operating system each time rather than passing only the handle of the
operating system's internal version of the pixmap.
open-pixmap-handle can be called again later to create a new device-dependent pixmap if desired. This function does nothing if the pixmap object already has no handle. Calling this function may be useful to save operating system pixmap resources (though a handle is not created and given to the pixmap object to begin with unless open-pixmap-handle is called to do this).
