[vtk-developers] Why not vtkTriangleFan?

Just out of curiosity...

Why is there a vtkTriangleStrip but not vtkTriangleFan?  Is it simply
because noone's implemented it, or is there a deeper reason lurking around?

It looks like using a triangle fan for something like vtkConeSource would
save almost 2*sizeof(vtkIdType) bytes per triangle.  That will add up in a
hurry when drawing large numbers of these - say, a few million.

Am I missing something?
