From: Jeff Mahoney <jeffm@suse.com>
Subject: cairo: Fix wrong allocation in _cairo_pdf_surface_add_source_surface
References: bnc#758422
_cairo_pdf_surface_add_source_surface allocates unique_id with
size unique_id_length but then copies surface_key.unique_id_length into it.
This causes e.g. evince to crash predictably while trying to print with:
*** buffer overflow detected ***: evince terminated
We should be using surface_key.unique_id_length instead.
