+================================================================================
++pcbnew:
+    More about copper zones filled without grid (by polygons)
+    Currently for eyes and tests only.
+    now working
+        thermal reliefs.
+        texts on copper zones.
+    To select this feature choose No Grid in zone grid filling.
+    Work in progress:
+    currently : not implemented:
+        Removing insulated copper islands.
+        trapezoidal pads
+
