Well, it brings up a few issues.. If someone defined a param spec with
a minimum/maximum value, Nan/Inf/-Inf are separate values that were
previously disallowed by the current code. So in my mind, making every
double param suddenly accept these values is a bit awkward. I'm not
sure how easily GParamSpecDouble can be changed to add new fields so
that params can specify whether they want to accept nan/inf
explicitly. That part was more of a RFC.. making the patch is easy but
I'm not sure what is an acceptable change.
