Google Maps - Moving marker to location based on map div size?

Question

Say I have a map div:

____________________
|                   |
|                   |
|                   |
|             m     |
|                   |
|                   |
|   x               |
|___________________|

m is where the marker is now (actually I don't really care where the marker is initially). I want to move the marker 5% div height, 8% div width from the bottom left corner to the x location (moving by pixels is okay too). Given that the map size can be of any size, how would I go about moving a marker from m to location x in the map.

Note: Just to clarify, I don't want the location(lat, lng) of the marker to change, but rather move the map such that the marker moves in the map div to location x.

Answer 1

OK, I put together something workable for close-up zooms (around 9 or higher). You will notice quickly at world-view zooms that it is horribly broken when the marker is near the poles or the International Date Line is visible on the map.

Well, it's a starting point. http://jsfiddle.net/TQ8YY/1/

Drag the marker to your area of interest.
