4 * i3 - an improved dynamic tiling window manager

7 * include/data.h: This file defines all data structures used by i3
10 #include <xcb/randr.h>
11 #include <xcb/xcb_atom.h>
19 * To get the big concept: There are helper structures like struct Colorpixel
20 * or struct Stack_Window. Everything which is also defined as type (see
21 * forward definitions) is considered to be a major structure, thus important.
23 * Let’s start from the biggest to the smallest:
