Tile borders show up when querying a polygon layer.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use the layer query functionality, as seen in the example layerquery.html
2. Change the query where clause to where: "STATE_NAME = 'Utah'",
3. Run the example

What is the expected output? What do you see instead?
I didn't expect to see the tile borders. Is there a way to change the opacity 
of the tile border when running a query. I tried using similar code to query 
and shade a states polygon layer and the results show a lot of really busy 
looking tile borders. 

What version of the product are you using? On what operating system?
I can't reproduce this in firefox, but you can see it in IE 8. I'm running 
Windows XP and using code from your latest build.

Please provide any additional information below.

Thanks so much for the hard work on this library! I'm attaching an image of 
what I see when querying a states layer.
