This is a matter of taste. I don't think restricting the flexibility of
the interface by not marking the functions virtual is justified by
anyones views on how a program should be written.

This is the sole disadvantage of making the functions virtual - that
they would not really be virtual in a full sense.

So, I think the manual should be changed to recommend allowing deriving
from cairo_t, since this seems to be agreed upon?

As for virtual functions, no-one seems to agree with me - so do as you
will!
