-- DEVELOPER WARNING - FOR OFFICIAL DEVELOPMENT --

-- Be careful when editig this script, do not introduce changes lightly!

-- This script is used for time records on the official Hedgewars server.

-- Introducing breaking changes means we have to invalidate past time records!

--------------

-- TO DO

--------------

-- allow scrolling of maps (was going to add this in the engine itself, but it can be done now by refreshing preview)
