Subject: [PATCH] Call cairo_surface_finish in ~Canvas when pdf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes an issue where when a pdf surface isn't buffered and then is
garbage collected, the toBuffer can be called and attempt to realloc
the destroyed closure.
