Description

The idea of client-side coordinate system transformations (in OpenLayers) has been discussed occasionally. In case it is decided that it is a good idea, I'm creating a patch for a suggested method of adding this functionality.

Using the above patch, you do transformations like so: 

var point = new OpenLayers.Geometry.Point(-100, 45);
var point_merc = OpenLayers.Projection.transform(point, "epsg:4326", "epsg:54004");

// or 

var feature = new OpenLayers.Feature.Vector(point);
var feature_merc = OpenLayers.Projection.transform(feature, "epsg:4326", "epsg:54004");
