QFG4: Pathfinding in forest 1S from Erana's Garden, south entry

[tomasz89]

The room south of Erana's garden has an odd pathing route when entering from south; the Hero walks NW then SE rather than simply entering the room.

[Vhati]

I can reproduce this in both the CD and floppy editions under ScummVM.
It does not occur in the original interpreters.

Same problem as #10858.

Room 580, entering from south (581). Or exiting to the south.

The SE poly extends across the center of the screen.

Interestingly, room 572 also extends across the center yet does NOT have a problem.
Its point on the screen edge forms a right angle, which hero can follow.

So far, rooms that need penalty workarounds (563 and 580) both have an acute corner.
