[Gimp-developer] Is there a way to update the cursor position from within a tool?

[Karl Günter Wünsch]

I have a problem. Because of the aspect pegging in the rectangle selection 
tool the cursor position and the corner of the area can move asynchronously 
because of rounding effects in conjunction with the set aspect ratio. 

That's why I would like to update the cursor position after all of the 
calculations are through to reflect the results.
