History: MovableTextOverlay

            !!Introduction
I started from ((ObjectTextDisplay|Xavier's ObjectTextDisplay)) example and eventually came up with these three classes, that do all the Text ((Overlay)) positioning for you.

The MovableTextOverlay class takes an Ogre ((MovableObject)), an Ogre String and a MovableTextOverlayAttributes pointer and 
makes your text moves with the Object on the screen, displaying it centered above the object (((HUD)) / heads up display).

The MovableTextOverlayAttributes contain all the ((Font)) / ((Material] / Colour Overlay attributes. I put them into a separate class with the intention of creating "groups" of MovableTextOverlay objects that share same "attributes".

The RectLayoutManager class is generic. It manages a list of non-overlapping rectangles within certain bounds. To find a non-overlapping position for a certain rectangle, it translates the rectangle on the Y axis until it finds a suitable position. I tried to optimise this class for speed as much as I could, any ideas are welcome.

Add a global vector to hold your MovableTextOverlay pointers

'''In your createScene'''

ÿ4ÿ

'''In your frameStarted'''

'''Media'''
