[vtkusers] rotating a plane

[Vincent]

Hi Marcio,

Thank you for your reaction. Creating a rotated plane is not really the 
problem, the problem is the interaction.  I would like to create a rectangle 
around a 2D object. This rectangle should have handles to rotate and scale 
the object (like in many drawing programs). I'm looking for some kind of 
widget with the desired mouse behaviour already implemented (or another good 
solution of course :) ).
Please let me know if you (or anyone) have a suggestion.
