One gets the curve and the location from the healed wire. However, the
curve has the original coordinates, the transformation the user used to
obtain it need to be applied before adding it to the surface builder.
Modifications for:
- let the surface workbench appear
- use only one Surface menu and toolbar instead of two separate ones
- create a Bezier surface using 2..4 Bezier curves (does not work yet)
- use enums for fill type
