Detailed Description

General 3x4 perspective projection matrix.

A class to hold a perspective projection matrix and use it to perform common operations e.g. projecting point in 3d space to its image on the image plane

    Modifications
       010796 AWF Implemented get_focal_point() - awf, july 96
       011096 AWF Added caching vnl_svd<double>
       260297 AWF Converted to use vnl_double_3x4
       110397 PVr Added operator==
       221002 Peter Vanroose - added vgl_homg_point_2d interface
       231002 Peter Vanroose - using fixed 3x4 matrices throughout
       250503 J.L.M. converted to pure vgl infrastructure and templated
              also made the interface a bit more consistent with
              plane projective transformations
       270603 Peter Vanroose - moved doc from .txx to .h
                             - implemented 3 NYI methods (get, set, set_rows)
