Choice between 2D & 3D appearance mode

[GuimDev]

3D appearance :

---

In my mind at the begin TF was like this with 3D appareance on the bottom of the screen, not 2D appareance (flat on the middle).

ProvisionsTeamFormation/header.lua

Lines 15 to 16 in 94e5598

	width = 600,
	height = 500,

I need to find a way to make circle border. #25

---

2D appareance only point ?

And 3D make blank arrow / bubble :
