Message:

added Coordinate, the interface MapSquare. MapSquares will be painted before MapSquares to avoid overlapping of them

Location:

applications/viewer/jmapviewer/src/org/openstreetmap/gui/jmapviewer

Files:

• Coordinate.java (added)
• JMapViewer.java (modified) (9 diffs)
• interfaces/MapMarker.java (modified) (1 diff)
• interfaces/MapSquare.java (added)
