Removing the default OL theme is unexpected

[gravitystorm]

In map.rb there is the line

@options = {:theme => false}.merge(options)

This removes the default theming from openlayers, and causes various controls (permalink, attribution) to pile up in the top-left of the map. Arguably this is a useful thing when you are trying to customise the look of OpenLayers, but you then need to supply the olControlAttribution etc style declarations yourself.

Either

• This code should be removed, to allow the default OL theme to apply by default, or
• This should be kept, and documented that you can revert to normal with something like theme: "/openlayers/theme/default/style.css", or
• This should be kept, and clearly documented that you will need to make your own style declarations covering the same range of things as is in style.css
