/*
 Toolbar settings (e.g. icon size or toolButtonStyle)
 =====================================================
 
 We have the following stack of settings (in order of priority) :
   - user-specified settings (loaded/saved in KConfig)
   - developer-specified settings in the XMLGUI file (if using xmlgui) (cannot change at runtime)
   - KDE-global default (user-configurable; can change at runtime)
 and when switching between kparts, they are saved as xml in memory,
 which, in the unlikely case of no-kmainwindow-autosaving, could be
 different from the user-specified settings saved in KConfig and would have
 priority over it.
 
 So, in summary, without XML:
   Global config / User settings (loaded/saved in kconfig)
 and with XML:
   Global config / App-XML attributes / User settings (loaded/saved in kconfig)
 
 And all those settings (except the KDE-global defaults) have to be stored in memory
 since we cannot retrieve them at random points in time, not knowing the xml document
 nor config file that holds these settings. Hence the iconSizeSettings and toolButtonStyleSettings arrays.
 
 For instance, if you change the KDE-global default, whether this makes a change
 on a given toolbar depends on whether there are settings at Level_AppXML or Level_UserSettings.
 Only if there are no settings at those levels, should the change of KDEDefault make a difference.
