Unless there is some sort of bug(*) or check(**) it should be you can do 
comparisons with inf (the sign should only be strictly needed for -inf).

(*) - There might be compiler flags which break the capability - see 
recent povray.unix posts. Testing what you expect to work involving 
+-inf in SDL is prudent. I'd not trust feeding these infinite values to 
functions SDL or VM ones for example.

(**) - The debug compile of the yuqk fork will often, but not always 
complain and stop/throw on seeing infinite values.
