[Vxl-maintainers] Re: vil_test_algo_cartesian_differential_invariants failed

[Peter V. <Pet...@es...>]

Dear all,

In core/vgl, most classes are templated on the data type (float or double).
But the vgl_polygon and the vgl_*iterator classes are not, which causes
some inconvenience when using e.g. vgl_polygon together with vgl_point_2d<double>.

I have now "templatised" all classes in vgl.  The "diff" of vgl_fwd.h is below.

This causes of course a (minor) interface incompatibility:
every user will have to replace every occurrence of   vgl_polygon  in his
private code with  vgl_polygon<float> .

Shall I go ahead and cvs commit my changes?
