Portrait positioning

AGS often makes some wrong guess about where the portrait of a character should be if you choose BasedOnCharacterPosition for Sierra-style portrait positioning. I made a post about it here:

Basically, when a character is the last character to have spoken, if nobody else talks in the meantime, it can travel anywhere on the screen and its portrait position will still be the same. I also found it strange that some general assumptions (i.e. the first character to speak could be assumed to be addressing the player instead of a random character) were not made.
