+    Default Pcbnew zoom values.

+    The last 2 values are handy when somebody uses a library import of a module
+    (or foreign data) which has a bad coordinate.
+    Also useful in GerbView for this reason.
+    Zoom 5 and 10 can create artefacts when drawing (integer overflow in low level graphic
