If this is for phobos it should follow a common model. But since 
a fast implementation might involve an object which builds a 
table before processing....

Another problem is that "precise" is a very loose term if the 
conversion is for display or for composition in a shader. What 
you want depends on the kind of post processing that happens 
after this and how it affects the nonlinearities of human 
perception.
