setBuiltInZoomControls(true) controls shown when paging

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Place org.osmdroid.views.MapView within a ViewPager* fragment
2. Show the controls, say by tapping on the map, and swipe to another fragment

What is the expected output?
The controls to swipe with the map.

What do you see instead?
The controls stayed in place (on the screen) and were visible over a completely 
different view / fragment until fading away.

What version of the product are you using? On what operating system?
<dependency>
 <groupId>org.osmdroid</groupId>
 <artifactId>osmdroid-android</artifactId>
 <version>3.0.8</version>
</dependency>

I worked around this by defining my own zoom controls:

    <org.osmdroid.views.MapView
        android:id="@+id/map_osm"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        cloudmadeStyle="1"
        renderer="CLOUDMADESTANDARDTILES"
        />

    <ZoomControls
        android:id="@+id/map_zoom_controls"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:paddingRight="8dp"
        android:layout_gravity="bottom"
        android:gravity="right"/>

        mZoomControls.setOnZoomInClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mMapView.getController().zoomIn();
            }
        });
        mZoomControls.setOnZoomOutClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mMapView.getController().zoomOut();
            }
        });

* android.support.v4.view.ViewPager

This is because the zoom controls are attached to the window and not the view. 
I don't know if there is a better solution than the one you have, but maybe we 
can review the way we use the zoom controls widget.

Zoom control should be tied to the Mapview, and not to the display.  Otherwise 
it acts as described when multiple fragment views are visible.
