It only displays objects which are on the screen

There are a few ways to get around the clipping for stuff like particle effects:
- use setshape and display the particles more in the middle of the npc, not at 0,0
- when using particles in ganis, you can put some visible or invisible graphics (1x1 pixel) somewhere outside the npc image to make graal think that the npc is covering a larger area, because it's calculating the area covered by the gani (only set the ani, not image or setshape)
