Ok. This means that the syntax of the setting and of the WPS will be the
same. But I don't think it would be a problem.

Another question: in viewport.h I see a declaration of the function
"viewport_load_config", but I couldn't find this function in a .c file.
Where is it defined and what does it do?

It was not particularly your code that I question, just the code I don't
understand. But that happened to be "yours" :-)

And another question: the function "viewport_parse_viewport" returns
VP_ERROR in the case of an error. The constant VP_ERROR seems to be a
bit combination and not a pointer. The combination just happens to have
the zero value which works, but isn't it dangerous? Wouldn't NULL fit
better?

I can of course provide patches for these remarks if you prefer but they
would be so trivial that I'm not sure it's worth the effort.
