MarkerCluster does not support image sprites

[GoogleCodeExporter]

It would be nice if MarkerCluster was capable of writing the image style with a 
top and left value, when defined.  This will allow us to use image sprites.

MarkerStyleOption will need a left and top value that can default to 0 or null 
and be handled appropriately in ClusterMarker_.prototype.createCss().

This should be possible in both MarkerClusterer and MarkerClustererPlus. 

In MarkerClustererPlus check out the documentation for the backgroundPosition 
property in the ClusterIconStyle array:

The position of the cluster icon image within the image defined by url. The 
format is "xpos ypos" (the same format as for the CSS background-position 
property). You must set this property appropriately when the image defined by 
url represents a sprite containing multiple images. The default value is "0 0".

That must be referring to the v3 version cause there is no MarkerClustererPlus 
for v2, which this tracker is for.

Thanks for the heads up though, I did not realize it was implemented in v3. :)
