    Are these "internal" routines supposed to be available to the
    applications programmer?

The Xlib XImage functional design is quite broken, and no one has had
the stomach to fix it.  The problem here is that XCreateImage obtains
several parameters from the display argument, there is no way to
specify explicit values when the data is coming from a file.  This
is ludicrous.  Since the internal functions stored in the XImage
can depend on these values, xwud is calling an internal function
to get the job done.  Perhaps, someday, this will all get fixed.
