make MarkerManager.prototype.updateMarkers_ just a little bit more efficient about google-maps-utility-library-v3

Hmm understanable issue.

MarkerManager was ported rather early in v3 development. There might be some 
pieces of code that might be updateable.

I will have a look at your suggestion, maybe i can make it more efficient, 
fresh look sometimes helps

I've had a quick look at the code, the fact is the markermanager removes the 
markers outside the viewport. This requires calculation. So, the set of markers 
might not have changed, the zoom might not have changed, but it does remove the 
markers outside the viewport to make dragging calculations as easy as possible 
for the API.

I might be able to check for other possible bottlenecks but i need a link to 
your page if possible. That way i can check it out with your example, see if 
there is anything in the profiling result that would help.
