SDPRCairo: enhance CairoPixelProcessor2D

Added and corrected quite some stuff to this basic
construct provided by Caolan (thanks again!). No
detailed descriptions here, but it's getting more
complete and faster.

May contain errors and is primitive-complete in the
sense that all gets rendered, but some basic stuff
that should be directly supported is still missing,
e.g. text rendering.

Adding this to allow people to check it out (speed)
also since it's not yet used as default in master,
so it's safe and also safes the changes publically.

To test it, use TEST_SYSTEM_PRIMITIVE_RENDERER as
set EnvVar in linux systems.
