Use the MousePosition Control to display the coordinates of the cursor
inside or outside the map div.
</p>
<div id="map" class="smallmap"></div>
<div id="coords" style="height: 1.5em;"></div>
<p>
This example also shows how to use the the "prefix", "separator" and
"numDigits" options to customize the output of the MousePosition-Control.
By also setting the "emptyString"-property, the contents of the controls
element are resetted to the given string when the mouse isn't above the
map.
</p>
<p>
Moving your mouse to the upper left corner of this map should return
'x=0,y=0' (pixel coordinates) -- in the past, it didn't in IE. If it
returns 'x=2,y=2', consider it a bug, and report it.
