1. Unification of the polygons creation (it is regardless of arguments order).
2. Output of 2dintersect DRAW-command was changed.
3. Geom2dGcc_Circ2d2TanRadGeo.cxx:
Precise intersection point found by Extrema Curve-Curve method (dot product between every tangent vector and vector between points on two curves must be equal to zero).
4. Some comments have been translated from French to English.
Some test case have been updated.
Changes in accordance with the last remark
Test case for issue CR25593
