Adjustment of playability (v0.3.0) — VDoll Steam update #563592

This time, I was working on improving features that I had found to be difficult to use. I think it has become somewhat better. First, the position and angle of the 'poses' that can be selected are now natural, even when 'Fix In the air' is turned on. For example, if you select the 'Doggy' pose, the doll will now crawl on the floor properly. This application was designed to be played without fixing the hip in the air. However, without fixing the hip in the air, it was inconvenient for casual play, although the degree of freedom was increased. Therefore, this modification has been made so that it can be played with the 'Fix in the air'. In addition, I worked on fixing a problem where the body would spin around on its own depending on the pose chosen when 'Fix in the air' was turned off. I believe it is less likely to happen than before because of the modification of the physical constraint...
