`M_PI, M_SQRT2`

#include "vigra/mathutil.hxx"

Since `M_PI` and `M_SQRT2` are not officially standardized, we provide definitions here for those compilers that don't support them.

        #ifndef M_PI
        #    define M_PI     3.14159265358979323846
        #endif

        #ifndef M_SQRT2
        #    define M_SQRT2  1.41421356237309504880
        #endif
