Jan Alexander Steffens 16160462a3 Use OVER operator for drawing text (#2908) 
For opaque text, SOURCE is not any different from OVER. However, when
drawing color glyphs (which consist of RGBA pixels instead of strokes)
SOURCE's handling of alpha is not what we want.

I stumbled across this because cairo 1.15.8 seems to clear the surface
before drawing color emoji if the operator is SOURCE, deleting every-
thing drawn before. Arguably, the area outside the glyph bounds should
not be touched, but even if this is a cairo bug the problem of alpha
within the glyph remains.

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.
