hi!
in my software renderer i managed some fixed point operations. this is pretty easy with SHL and SHR. but now that i want to implement new stuff to my polygon-fill-routine, i would have to change everything. but all i get is confuseness and errors because those fixed opperations are just to over complicated when i do it my way. is there a library or a class which supports them more effective? because they are two times faster than floats or int64... :/
