In addition to my own code, this addon uses de code of two other addons:

BigDebuffs by Jordons (version 1.6 which was released in a public domain licence)
http://www.curse.com/addons/wow/bigdebuffs

and

Mouse out Range Pointer by Gello (code modified from version 1.1.4)
http://www.curse.com/addons/wow/mouseover-out-range-pointer

I asked both authors and both authorized me using their code (modified or not) inside this addon and for that I am greatful.
