19/* This class is a really tiny filter around QLightDM::Greeter. There are some
20 operations that we want to edit a bit for the benefit of Qml. Specifically,
21 we want to chop colons off of any password prompts. But there may be more
22 such edits in the future, and by inserting ourselves here, we have more
23 control. */
