commit f215b38c7e880251ebf99e9fdcf428ee4eb7e60d
Author: Matthias Clasen <mclasen redhat com>

Seal PangoItem
Add getters to access the current fields of
PangoItem and PangoAnalysis, and hide the
structs.
pango code and tests still access the structs
directly, but examples and utilities have been
ported to the getters.
