That's very interesting, but having looked at the sample picture and the
documentation describing the feature, I think I can do better than that.
I was intending to write my patch so as to be compatible with this one
(i.e. the same scene file can be made to use the other one just by
changing a single parameter) but looking at the syntax this patch uses
we seem to have completely different ideas about how it should work.

My project will go forward as planned; I may decide to run off a few
simple pictures using this patch for comparative purposes in the
'evaluation' stage, but I will not even be looking at the code.
