Looks good to me.

There is a question in my mind.
Converting strait alpha to premultiplied alpha is no problem, but lossy.
However, Converting premultiplied alpha to strait alpha make me feel bad
because it is lossy.
But, it seems that Cairo port is also doing premultiplied alpha → strait alpha
conversion.
