Scale factor simplified and zoom speed fixed to be constant (always multiply/divide scaling factors...). If the map is rotated in pan mode, the panning is rotated likewise (V2_Rotate added and exported for this purpose; the other V2 functions would be good candidates for exporting as well).
The messages about "follow off" and "follow on" had the ON and OFF the wrong way around.
Initial positioning of the automap at the start of map is always on the player.
When pan mode is active, closing and reopening the automap will not affect the current position of the panning.
