// I am ripping this code apart a little, because shapes really should not involve tile sizes in their x/y calculations.
// I'm not sure why this was ever done this way, as TMX gives the X/Y and width/height already. The old way was basically to convert
// the x/y coordinates into tile based coordinates and then re-convert back to full x/y coordinates. This makes no sense any more to me.
//
// Having examined TMX format a little more, it seems that the x/y position is always specified
//
//float fx = x;
//float fy = y;
//if ("orthogonal".Equals(tiledMapSave.orientation))
//{
// fx -= tiledMapSave.tilewidth / 2.0f;
// fy -= tiledMapSave.tileheight + (tiledMapSave.tileheight / 2.0f);
//}
//else if ("isometric".Equals(tiledMapSave.orientation))
//{
// fx -= tiledMapSave.tilewidth / 4.0f;
// fy -= tiledMapSave.tileheight / 2.0f;
//}
//tiledMapSave.CalculateWorldCoordinates(
// 0, fx / tiledMapSave.tileheight, fy / tiledMapSave.tileheight,
// tiledMapSave.tilewidth, tiledMapSave.tileheight,
// w * tiledMapSave.tilewidth, out newx, out newy, out z);
