Fixed bug when changing stereo base after setting view mode

[Problem] When setting new stereo base using SetStereoBase() function, camera position was incorrect
[Cause] SetPerspectiveProjection() function modifies the z coordinate of the camera
[Solution] Set the correct position, not only x coordinate, after calling SetPerspectiveProjection() on each camera
