Short description of error
I add some TEXT in GBE's 3D sence,I hope player can see the TEXT backface when they are walking around. But, in general, TEXT backface can not show in BGE. One day, suddenly, I found a way can do it.

Very easy, just add a mesh, disable Backface Culling in Material, ( Linux system need: enable Transparency & Use Z Transparency), so TEXT backface show. ---- It's very useful for my game, but I think it's a BUG, I hope Blender can keep this function by the right way.

Exact steps for others to reproduce the error

(1) Add two Text in BGE, one face to you, another rotate 180 degree backface to you.
(2) Press P test game, you can see only one Text, the one face to you.
(3) Add a mesh object -> Give it a Material -> Game Settings -> disable Backface Culling.
( If in Linux System, mesh object's Material -> must enable Transparency & Use Z Transparency)
(4) Now, Press P test game, So the Text backface show! You can see two Text objects now.

Just one mesh object disable Backface Culling can let TEXT backface show, other objects can still keep enable Backface Culling.

Show TEXT backface is very useful, I hope Blender can keep this function by the right way.
