These insets should be display density dependent, they look not so well on an ldpi device.
I'd apply a construct like:
```
    // preliminary default for mdpi screens
    private static int VISITED_INSET = 7;

    public static void initializeScale() {
        // Calculate visited inset based on screen density
        VISITED_INSET = (int) (6.6f * cgeoapplication.getInstance().getResources().getDisplayMetrics().density + 0.5f);
    }
```
