Polygon Class

[Michael Thaler]

Hello,

I want to port the Cubism filter from gimp to Krita. The filter uses a polygon 
class. This class just stores points as double values and can rotate the 
polygon and translate the polygon. Is there any class that already does this 
in QT, KDE or Krita? If not it is simple to write this class, but I think it 
is more of more general use. Where should I put it then? In krita/core?

Greetings,
Michael
