Here is a version of the file that will compile against SVN (the only
problem was the change from Object::cloneAs to the template clone()
method).
Also, you'll need to change the IMAGE_PREFIX to something so that the
viewer can find the images it needs; maybe /tmp, or something like that.
We'll work a better solution for that later, as it is largely my own bug
(not one Cedric introduced :))
