[SDL] Problems with text rendering using TTF

[Nuno Santos]

Hi,

I'm not very inside of the OpenGL api details but i tought i could  
get some extra performance using display list to store textures...

I took this example from OpenGL superbible.

Well, they are working and i don't any problem with compilation with  
my program so far.

But, can this explain why i have textures being applied to the are  
that i'm using to create text with SDL_ttf?

Cheers,

Nuno
