* After any change to this list of macros the file /CheckIcons.sh needs to be
* updated accordingly, to ensure that the icon names of the affected macros are
* still considered in the extraction.
*
* The naming pattern of the macros is like this:
* * koIcon* returns a KIcon object
* * koIconName* returns a QLatin1String (aligned with usual API where "iconName" property is of type QString)
* * koIconNameCStr* returns a const char*
