[gdk-pixbuf/resources: 2/4] Add gdk-pixbuf-pixdata program

[Alexander Larsson <alexl src gnome org>]

commit d67b4bb82c620d318089f2a2285e40a6f00d0340
Author: Alexander Larsson <alexl redhat com>
Date:   Tue Jan 31 14:46:39 2012 +0100

    Add gdk-pixbuf-pixdata program
    
    This is similar to gdk-pixbuf-csource, but it generates raw
    binary GdkPixdata files.
