[cairo] Regression in PDF backend

[Behdad Esfahbod]

Hi,

With master I'm seeing a regression in the PDF backend where the linear
gradient is coming out as all black.  It used to work with a snapshot of
a few weeks ago.

The code to test this can be found in this git repo:

Just run make pdf.

Cheers,
