* DictQuickLookup: Preserve alpha when switching dict, and scrolling inside a dict. * Start moving the NumberPicker alpha hack to Button itself This makes handling flash_ui easier and saner, avoiding flickering. * Handle the transparency hack entirely from within Button * Murder the now unnecessary NumberPicker update_callback hack * Tweak comments * And the Button handling made that redundant, too * Squish debug print * More comment tweaks * Reset transparency on scrolling instead of rpeserving it * Reset alpha when switching dictionaries * Simplify the pre/post callbakc transparency state handling And explain why we need to care. * Give a named reference to ButtonDialog's MovableContainer, so the Button alpha hack behaves with it * Document the "self.movable" convention * Amend that comment a bit e.g., we don't care much about MultiConfirmBox'w MpvableContainer, as any button action will close it. * And make SkimTo's MovableContainer accessible so that Button can grok that it's translucent
