0023361: Bug in gp_Trsf::Multiply

Browse Source 
Bug in gp_Trsf::Multiply fixed.
If we multiply 2 gp_Trsf objects (shape == gp_Rotation), for example, t1 * t2, and t2.loc = 0
(t2.loc.x == 0 and t2.loc.y == 0 and t2.loc.z == 0)
then t1.loc will not change (you can verify it from the matrix multiplication)
Adding test case
