[cairo] RFC the idea of n-plane color support

[Jost Boekemeier]

[We want to avoid color space conversions because
after the conversion the backend may no longer be able
to restore the original color.  For instance a printer
may choose to mix the color instead of using the color
from the appropriate ink cartrige]

Not really.  A token that describes how the following
color tuple must be interpreted should be enough.

That's why I've asked how PDF and PS solve this
problem.
