The problem I see is how do we ensure that the original intent of the
Eagle design is preserved when it's imported into KiCad.  We can import
graphical items to copper but should they be imported as graphical items
or converted to custom pads.  Is there any way to tell the difference in
Eagle?  If not, then the user may have to perform a manual conversion if
they want to use them as a pad.  JP, do you have any concerns about this
patch?
