title: Gmaps4rails: scaling (not zooming) a gmap
body: <p>I am using gmaps4rails and I have a set of dynamic generated markers, about 14, that I display across the globe.  I use auto_adjust and it looks good, however, it seems that the size that I have chosen for the map fits perfectly between two zoom levels. It either shows too much of the map (e.g. you see asia on both sides) or if I zoom in one level, I don't see some markers.
  The css width and height we have chosen is what we want to fit in the window.  Smaller or larger (to match the two zooming levels) wouldn't look as good.
  The goal being, a larger image, but staying at the same, fixed, zoom.
  Is there a way to scale the map, like you can with images?</p>
  
  <p>I am using rails 2.3.11 and had to copy in the js/css assets and modify/override the gmaps4rails view.  I am not using the gmapable module.</p>
