An altered version of
display() which displays the text scrolling, letter for letter, simulating that it is being spoken.
Background can be either an image or an object, and will be displayed as background while the text is being displayed.
Person can be either an image or an object. If an image is parsed it will be showed as a portrait for the person in the text box next to the text. If an object is parsed it will display the name of the object before the scrolling text in addition to using the image of that object as the portrait. Name can be used to parse another name than the name of an object.
