# The options of a widget are described by the following attributes
# of the Pack and Widget dialogs:
#
# Dialog.current: {name: value}
# -- changes during Widget's lifetime
#
# Dialog.options: {name: (default, klass)}
# -- depends on widget class only
#
# Dialog.classes: {klass: (v0, v1, v2, ...) | 'boolean' | 'other'}
# -- totally static, though different between PackDialog and WidgetDialog
# (but even that could be unified)
