Comment #5 on issue 450 by alexandr...@gmail.com: Non embedded edges culling in Mondrian http://code.google.com/p/moose-technology/issues/detail?id=450
it works. But it can be optimized I think. For example, I check if the bounds given by the current window frame intersect the rectangle bounds of the edge. This is clearly not optimal since we should check if the line crosses the window frame.
