What this settings are? And how big is the perfomance loss?

Don't know ;). Perhaps poor design: it's not the way GTK Object System
It can be harder to read. Also it's better to cast objects if it means
easier debug AND there is no perfomance lost in production code.

I only need to hear about the debug settings you told me. If there is
a bit extra typing and no perfomance loss (in production code), I would
very happy to write programs in C and casting everywhere :).
