[ggt-devel] GMTL enhancements

[Paul M. <pm...@sk...>]

Hi -- I'm submitting a patch with two enhancements:

  * a new setLookAt() function in Generate.h (implements gluLookAt())
  * a new binary operator^() for Vec3 cross product in VecOps.h

Note that setLookAt() makes use of the new cross product interface. This change 
is based on svn trunk r1277.

Thanks,
    -Paul
