You have a very goog product named WebGlEarth. But....
I have some picture .png (may be .jpg) and I don't want to overlay it as
map with MapTiler. But I'd like to do it as a WE.poligon, for example.
Can I do it in WebGlEarth as in GoogleMaps API? May be, you are planning
now to add the same tool in the nearest future? May be WE.overlay is already waiting us anywere and I know nothing?
Thanks in advance for your answer.
