Comment:

 I can confirm that this works for now, but in general I would prefer if
 all those things (resolution, scale, units) would be updated on the map
 object in the map.setBaseLayer method instead of using an expensive getter
 method to fetch this from the base layer every time it is needed.
 Especially for getResolution, which is called for every single feature
 during vector rendering, this would really increase performance.

 Please commit, but I'll create a new ticket so we don't forget my
 concerns.
