 * Macros to support collecting the icons in use.

 * 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 QIcon object
 * * koIconName* returns a QString
 * * koIconNameCStr* returns a const char*
