-----------
Fix GPU deformable model rendering to improve performance. The problem was some 
inefficient normal/tangent/binormal transform using skinning. Now the 
performance increase from 200fps to ~1000 fps on GTX560 card for rendering a 
single ChrBrad character. 

Fix Data Viewer rendering problem : The camera is now set correctly to view the 
chart. The font texture is initialized correctly so it won't go bad after 
closing the window.
