[vtkusers] Colour a triangle

[Naoko TAKAYA]

Dear VTK-users,

I've just solved the problem... sorry... ;-)

But just one more thing.

I changed the vtkFloatScalars to vtkUnsignedCharScalars to
solve the problem, but why does vtkUnsignedCharScalars work
and not vtkFloatScalars. although the coordinates are in 
float ?

Any advice is very much appreciated ;-)
