As everyone know. A animation is various frames drawned one after other.
To create a animation, the current frame and the previous frame have to
looks like, however have to have a difference. To this happen you have to
look the current frame and the previous frame, and then check if is
changed correct and if is changed where you want.
That waste a time. Because you have to toggle the visible of frames to
check and check until you have certain that is correct.
Well, the solution is very very simple. Is just make the previous frame
50% transparent. Then the current frame will have a shadow of the previous
frame. This way you can see what is what.
