[Xcb] DefaultScreen

[Vincent Torri]

Hey
I have decided to rewrite ecore_xcb. There are too many problems right
now.

Before, I would like to add in the tutorial how to translate the Xlib
functions like DefaultScreen

And about DefaultScreen, as I talk about it :D, how can I get it ?

in xcl (old version), it's:
dpy->fd = XCBOpen(display_name, &dpy->default_screen);
which is strange as XCBOpen takes an int and not an int * as 2nd
parameter.

So, i'm a bit confused.

thank you

Vincent
