void basegfx::utils::createSinCosOrthogonal (double &o_rSin, double &rCos, double fRadiant)
 If the rotation angle is an approximate multiple of pi/2, force fSin/fCos to -1/0/1, to maintain orthogonality (which might also be advantageous for the other cases, but: for multiples of pi/2, the exact values can be attained. More...
