In ProjLib_ComputeApprox algorithm, compute correct parametric tolerance from the input 3D tolerance using surface resolution, in order to pass it to low-level 2D algorithm Approx_FitAndDivide2d (instantiation of the generic class Approx_ComputeCLine). Earlier 3D tolerance was used as parametric tolerance directly, which was a problem for surfaces with too small radius of curvature. Also, eliminate redundant creation of the object of type AppParCurves_MultiCurve on each iteration in the method Approx_ComputeCLine::Compute. The post treatment of the Edge/Edge intersections has been improved. Namely: a. Making the procedure of sharing Edge/Edge intersection vertices consistent with intersection algorithm by enlarging bounding box of each vertex on half of Precision::Confusion(); b. Algorithm of computation of vertex tolerance (in order to cover tangent zone between Edges) has been changed for Line/Circle cases. Test cases for issue CR27804 Adjusting test cases according to their new behavior. Mark the test boolean/volumemaker/A8 as unstable between different versions of MSVS (2010 and 2013).
