07-Nov-2006: (prissi) FIX: elevated construction could only connect via straight connections FIX: tunnel rails were upraded to even higher speeds than allowed FIX: no more accidental connection between bridges/tunnels FIX: no more upgrading track on bridges or in tunnels FIX: way search for ways below monorail fixed CHANGE: unified construction of rail, monorails, maglev, channels, airstrips by baue_schiene() FIX: position now nearly always centered for all zoom levels and pak sizes FIX: scrolling with right mouse button for all pak sizes FIX: rectangle in minimap now shows the real screen size (these three were in for ages ... ) CHANGE: (tron) assembler corrections, code cleanup, reader definition more C++ style CHANGE: tunnel code changed (might not load 99.03 savegames!) CHANGE: 6 byte less for planquadrat_t (i.e. per tile, although GCC gives us only four of them) CHANGE: 8 byte less for grund_t => 14 bytes less per tile (12 with GCC) => map requires ~ 15-25% less memory CHANGE: rewrote dingliste: alsways well defined position, about 10-20% faster insert of vehicles CHANGE: articulated vehicles are now always bought together, if there is only a single choice
