Comment 31 for bug 895003

I think sequence for vehicles is not needed. But the art ini tags for shp vehicles should extend:
- Support slopes
- Support death frames
- Support aircraft

No more.
SHP vehicles types already support idle animations.

Some are already fixed to.
Like in vanillia, hover or ballonhover shp vehicle must have turret or they cant have shadow. This is fixed, which is very nice.

SHP vehicles dont need tags like prone, random idle animation, swim, pannic, crawl and so on, its a waste of time if you ask me.

Edit: support slopes for shp vehciles with turret is probably impossible. So I dont know about extending shp units is a good idea.
