When a map generated with mkgmap is displayed in MapSource the background is not aligned with the map.
The background’s boundary rectangle is smaller than the map’s boundary rectangle.
It need to be larger on the right side and at the bottom.
It is correct at the left and top side.
Also when a selection of that map is done the rectangle is neither aligned with the background or
the map, it somewhat something between.
It is correct on the GPS unit!
I use mkgmap-r1785
