[cairo] Cairo + GdkPixbuf

[Krzysztof Kosiński]

Hello

The fact that Cairo cannot understand non-premultiplied RGBA which is
used in GdkPixbuf is somewhat inconvenient.

I have some questions:
1. What is the amount of work necessary to add support for a new pixel
format in the image surface?
2. Does supporting N pixel formats require O(N) or O(N^2) code?
3. Which points made here are still valid [1]?
