MarkerClusterer not functioning

[GoogleCodeExporter]

You can resolve this by changing the line
var pos = this.projection.fromLatLngToDivPixel(latlng);
to
var pos = this.getProjection().fromLatLngToDivPixel(latlng);
in ClusterIcon.prototype.getPosFromLatLng_

... this may be due to a change in the OverlayView part of the API or 
something...

Just to second the suggestion by friism - in the
ClusterIcon.prototype.getPosFromLatLng() function of markerclusterer.js, change 
the
"...this.projection..." line to be "...this.getProjection()...".

Apparently the projection variable was never meant to be exposed, and was taken 
away
in the release on 11th May, according to this thread:

sorry, typo above. The function is ClusterIcon.prototype.getPosFromLatLng_ , as
friism said.

I am still getting issues in Firefox on the examples page: 
http://google-maps-utility-library-v3.googlecode.com/svn-history/r88/trunk/marke
rclusterer/examples/advanced_example.html?

firebug:
this.projection is undefined
var pos = this.projection.fromLatLngToDivPixel(latlng); 
markerclusterer.js (line 830)

I have not tried the fix mentioned in the comments yet.  If this is such an 
easy fix, why can't a committer fix it?

I tried the fix.  Now the map is not loading - it loads the gray background, 
but nothing more, and then hangs.  I get a JS timeout in the main map API in 
Firefox, without any errors.  I've tried commenting a lot of stuff out, 
including data and markercluster so IDK - might be an unrelated bug.

I'm still having issues on the example page as well:
too much recursion
function md(a){return function(b){if(!... ("+(c[jc](" | ")+")")))));return k}}
main.js (line 16)

I am thinking I should just stick with v2....

Ok, so the map not loading was me passing in undefined/null when setting the 
center.  (Sorry for spamming, but I did not want anyone investigating it) 

I have markercluster working in v3 now.  It does not feel faster/better - but I 
am going to set v2 up in parallel and do some benchmarks.

This was fixed a while ago, I just forgot to check the issue tracker :)
