You know there's little point in asking a question if you're going to right 
away answer it yourself in a condescending manner. It's passive aggressive and 
it's irritating.

Attitude aside that's not what the difference between <> and "" is. In fact the 
standard says that the difference is implementation dependent. Our most common 
compiler says this:
http://gcc.gnu.org/onlinedocs/cpp/Include-Syntax.html

#include <file>
    This variant is used for system header files. 
#include "file"
    This variant is used for header files of your own program. 

So the reason it's done is because:
a) according to our favorite compiler "" is used for header files of your own 
program, which gallium headers are,
b) most importantly, especially for people using different compilers on 
different systems where the differences between <> and "" can be arbitrary: 
because it's the style that is used by the rest of the project.
