[cairo] cairo_win32_printing_surface + no-print-out no-crash

[Dominic Lachowicz]

Hi,
You still need to call StartDoc/StartPage/EndPage/EndDoc in the right
places. The printing surface (as opposed to the "normal" win32 surface)
merely outputs high-quality GDI-based vector drawing commands as much as
possible. Interacting with the printer is still the caller's responsibility.

Best,
Dom
