[Graphics] Shutter and opened door ignore conditions of ground tile.

[Aerotinge]

Shutter:
As you see there, right half of shutter tlie shows a high-lighted green ground, not moss covered ground nor normal ground(two o'clock position)
It seems that right half of shutter tlie is not rendered correctly.


Opened door:
Same as what has been written above. Inside a opened door frame, it renders a high-lighted green ground.


Not really a problem of gameplay, but a little problem of immersive.
