Do you think it will be portable when converting special values from 
signed integers? As I read the specs, converting NaN with 
(u)intBitsToFloat() is already undefined, but seems to work. Won't 
representing specials through signed integers be leaving more room for 
different behaviour on various cards, drivers and GLSL versions? I can 
sure make it and test on what I have here, but it seems hard to be sure 
how universally this will work.
