Something like this is still the basic plan for allowing color input
outside the range of 8-bit sRGB. Perhaps a floating-points surface
type as well. And note that the API for specifying color
(eg. cairo_set_source_rgb) is already floating-point. So the only
missing API here is for allowing floating-point surface input as well.

But there's also a missing implementation, and I'm not aware that
anyone has started working on this area yet.

I don't expect much to change here before 1.2. I really want to get
that release out already, (that is, months ago).

I will be attending the upcoming Libre Graphics Meeting:

and I hope to be able to have some good discussion on color there. (As
in, please come and teach my clueless self how color works/should
work.)
