What I'm trying to achieve is this:  For the demo, I need an example
image file to process (maze.png).  However, when this file is installed
in the package directory, I need to find out where exactly this is in
order to read the file successfully.

The "best" way to do that I found so far is to use mfilename() from a
function in the package directory (where also maze.png is installed).
This function is __levelset_getdir.

But if you know a better way to locate and read maze.png from within the
demo, please let me know.  I could of course ask the user to enter the
path to one of their own image files, but I think this makes the demo
too tedious as an example.

Yours,
Daniel
