0027119: Regression: Draw command "incmesh" hangs on the attacheced face.

Browse Source 
BRepMesh_CircleTool: extend radius of circle by quite small value in order to classify points forming inscribed triangle as lying on it. Do not use PConfusion due to false positive result leading algorithm to hanging.
