Re: unsigned byte color!

Not to sound stupid, but why does your lua say:

myColor= Color4i(255, 0, 0, 100);

according to the luabind registration code, it should just be...

myColor=Color(255,0,0,100);

And lua internally supports plain ol' intergers ( int32 ...ok depends on
platform but you get the point...)

so no matter what happens, this is likely going to be cast at runtime.
have a look at the c api for details as to the very minimal types
supported w/in lua.
