Updates to 2D fillet and chamfer

As I mentioned in last week's post about the 2D fillet and chamfer tools, they created new generic shapes that couldn't be edited or extruded. Today I updated the tools to create known shapes.

For the chamfer, the resulting shapes are three lines. The new line's extremities are obtained by building a helper circle, with the center in the two lines' intersection point and the radius equal to the chamfer's radius:

For the fillet tool we need to create an arc and two lines. To determine the arc's center, we draw two additional circles (magenta) with the fillet's radius and the centers in the intersection points obtained from the first circle (lime green):
