Hello,

I'm developing a mashup using Google Maps, we have thousands of
markers inside. One thing I would like to do is at the end of the
movement of the map (moveend event) to list the markers in the
viewport in a list element.

Nowadays, I have a function in the moveend event for the marker, and
for each marker that is contained by the viewport I append a new
element in the list. This approach it's a bit slow, so with 1000
markers, i have to enter 1000 times in this function.

I want to change my approach, and I'm thinking in:

1. Get just the markers in the viewport
2. Add it to the list.

In this way, if the 1st function is fast, we work just for few markers
instead of 1000.

The 1st point is where I have doubts, so: Is there any function that
gives me the current markers inside the viewport? This functions loops
for all the markers or it makes any optimization?

Thank you very much,

Lluís
