Under python, the class vtkTkRenderWidget appears to contain a small bug (VTK
3.1.2 distribution, vtkRenderWidget.py)...
In the member function UpdateRenderer(self,x,y) the transform to local window
coordinates includes the lines
vx = float(x)/windowX
vy = (windowY-float(x))/windowY
i.e. the x-value is used for both coordinates!
In the same function the variable self.__RendererFound is not initialised to a
default value. In combination with the above problem, this was found to give
an AttributeError exception under some circumstances.
