App 2.39.2: Grid with map seen from higher up

The map gets its own camera, tilted 45 degrees down from about 300 m up,
so roads keep their shape some 400 m ahead instead of collapsing into
the horizon. In map mode the floor starts at half height, the speed is a
little smaller, the floor's grid is fixed to the ground and turns with
the roads, and the power disc has a dark backing.
