/**
* Iconloader for KDE.
*
* TDEIconLoader will load the current icon theme and all its base themes.
* Icons will be searched in any of these themes. Additionally, it caches
* icons and applies effects according the the user's preferences.
*
* In KDE, it is encouraged to load icons by "Group". An icon group is a
* location on the screen where icons are being used. Standard groups are:
* Desktop, Toolbar, MainToolbar, Small and Panel. Each group has some
* centrally configured properties bound to it, including the icon size
* and effects. This makes it possible to offer a consistent icon look in
* all KDE applications.
*
* The standard groups are defined below.
*
* @li TDEIcon::Desktop: Icons in the iconview of konqueror, kdesktop and similar apps.
* @li TDEIcon::Toolbar: Icons in toolbars.
* @li TDEIcon::MainToolbar: Icons in the main toolbars.
* @li TDEIcon::Small: Various small (typical 16x16) places: titlebars, listviews
* and menu entries.
* @li TDEIcon::Panel: Icons in kicker's panel
*
* The icons are stored on disk in an icon theme or in a standalone
* directory. The icon theme directories contain multiple sizes and/or
* depths for the same icon. The iconloader will load the correct one based
* on the icon group and the current theme. Icon themes are stored globally
* in share/icons, or, application specific in share/apps/$appdir/icons.
*
* The standalone directories contain just one version of an icon. The
* directories that are searched are: $appdir/pics and $appdir/toolbar.
* Icons in these directories can be loaded by using the special group
* "User".
*
