How is the performance?

I haven't had the chance to test your examples yet but I figured I could just ask you directly if you've done tests with heavier drawing and if you can comment on the performance. After all, cgo is known to have a rather large overhead compared to using just Go or just C.

@martinsotirov Hi, no I didn't test the latency of drawing frames using cairo, but cgo overhead is very small, also commands can be batched, if this becomes a problem.

@xlab, ok, thanks. I'll put together a more stressful demo when I get some free time, and I'll report on my findings.
