0025194: It is necessary to orthogonalize transformation matrix in gp_Trsf and gp_Trsf2d classes

Browse Source 
1. Method "SetValues()" for gp_Trsf2d class is added.
2. Method Orthogonalize for gp_Trsf2d and gp_Trsf classes was added.
3. Unused arguments from "SetValues()" method for gp_Trsf was deleted.
4. Output of AppParCurves_MultiPoint Dump  was corrected.
5. Method of right projected point choosing was corrected in ProjLib package.
6. Some test cases were changed according to their new behavior.
