Comment (by bartvde):

 Hi Tim, another question about this. Why is map.zoomTo not adapted to also
 take in floats? When I want to zoom now to a fractional level I have to do
 the following detour:


 {{{
 var zoomLevel = this.map.zoom + (deltaY/this.zoomStopHeight);
 var scale = OpenLayers.Util.getScaleFromResolution(
     this.map.getResolutionForZoom(zoomLevel), this.map.units );
 this.map.zoomToScale(scale);
 }}}

 Whereas I would want to do:

 {{{
 var zoomLevel = this.map.zoom + (deltaY/this.zoomStopHeight);
 this.map.zoomTo(zoomLevel);
 }}}
