When downloading the whole world and rendering tiles based on that, these 
tile-crossing problems of the name-suppression should vanish (or at least 
be reduced a lot :-)

Making it dynamically should not be a problem. When properly cached, then 
also CPU power should be no problem.

At the beginning I would not think providing i18n captions is a good idea 
from t...@h, but captionless tiles allow others to make such stuff.

Also I think instead of rendering captions at all, the captions should be 
passes as position+direction+text information and rendered when 
displaying. But that is probably a future project :-)
