Subject: Tile-manager: kill off tile-refresh.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=cb087dc4def164eadaae6f7262892feb9ec2a8ca;p=flightgear.git

Tile-manager: kill off tile-refresh.

Now the manager waits on terrasync, we never need to do the
'experimental' refresh feature, since we only load finished tiles.
