hidden transformation of wavefront obj models

[rainergericke]

There seems to be some hidden transformation in vsgXchange v1.1.7 during the load process of obj modefiles. Please try this with the attached model file:

vsgviewer hmmwv_chassis_simple.obj

then convert it:

vsgconv hmmwv_chassis_simple.obj hmmwv_chassis_simple.vsgt

at last view both files:

vsgviewer hmmwv_chassis_simple.obj hmmwv_chassis_simple.vsgt

One of the model files gets a wrong rotation.
