    Fix loading renderer DLLs on Windows x86
    
    After 'Fix floating point precision loss in renderer', Windows x86
    client won't load the renderer DLLs. The problem is a 64 bit modulus.
    I couldn't find any reports of this online. However, client with
    built-in renderer worked with the 64 bit modulus.
    
    Only tested with mingw-w64.
