* CM 2pass spec with only ambient color is not working
* 2 materials with same name is not working as expected (error message?)
* fix problem with "show base vectors per triangle"
* base vectors compressable from 12 bytes to 4
* redo samples  - because of tangent space changes

* After screensaver the 3d view is not restored - after minimize and maximize its working again

* normalize approximation from http://gamestudies.cdis.org/~amatheson/LUA-Part01/Part01-section01.html
  Normalize(V) = V/2 * (3-V*V)     form angles <40 degrees

  Use Newton-Raphson approximation in pixel shader (an idea from Tomas Arce presentation at GDC2002): mul r0, LightVector, 0.5
  dp3 r1, LightVector, LightVector
  mad r0, 1-r1, r0, LightVector
