Bug in InteriorInstance::castRay()

This is a bug that's been in TSE since my first checkout in Dec 2004:

bool InteriorInstance::castRay(const Point3F& s, const Point3F& e, RayInfo* info)
{
   info->object = this;

   if (mInteriorRes->getDetailLevel(0)->castRay(s, e, info)) {
      PlaneF fakePlane;
      fakePlane.x = info->normal.x;
      fakePlane.y = info->normal.y;
      fakePlane.z = info->normal.z;
      fakePlane.d = 0;

      PlaneF result;
      mTransformPlane(getTransform(), getScale(), fakePlane, &result);
      info->normal = result;
      return true;
   }
   return false;
}

As you can see InteriorInstance::castRay() is transforming the normal into world space. Well the problem is that Container::castRay() also transforms the normal... so your hit normals are transformed twice for hits on interiors.

Looking at TGE 1.4 it does this properly:

bool InteriorInstance::castRay(const Point3F& s, const Point3F& e, RayInfo* info)
{
   info->object = this;
   return mInteriorRes->getDetailLevel(0)->castRay(s, e, info);
}
