Ingo Bürk bf442ff5de Make freeing surfaces idempotent
If a window with border is set to "border none" and then closed, we would
call cairo_destroy / cairo_surface_destroy twice, causing an assertion
failure in cairo as the objects already had zero references the second
time. We fix this by explicitly setting these objects to NULL.

Introduction
============

libi3 is an *INTERNAL* library which contains functions that i3 and related
tools (i3-msg, i3-input, i3-nagbar, i3-config-wizard, i3bar) use.

It is NOT to be used by other programs.

Structure
=========

Every function gets its own .c file, which in turn gets compiled into an .o
object file. Afterwards, all .o files are archived into one static library
(libi3.a). This library will be linked into all i3 binaries. The linker is able
to eliminate unused .o files when linking, so only the functions which you
actually use will be included in the corresponding binary.
