[Openicc] GoSoC 2011: CPD and target printing

[edmund ronald]

Chris,

 I say applications should have all options open at the behest of the user,
including printing targets.

 You and Mike both say that "special" apps only should be able to print
targets.

 Mike has made a very nice printing system that can just about print
anything except a target.

 I say that if you really want to print targets you are welcome to write an
app to print targets, as it's pretty clear that otherwise you won't get one
:)

Edmund
