ENH: improve generate_contact_points tree support

Browse Source 
1. Previously we used integer Point type to detect corner, which was wrong.
2. Delete duplicate points more aggressively to prevent too many points
   around curved overhangs.
3. Do not generate roof_1st_layers if there is no interface at all.
