Returns the actual size of the icon the engine provides for the requested size, mode and state.
The default implementation returns the given size.

overridevirtual |
Called by QIcon::addFile().
Adds a specialized pixmap from the file with the given fileName, size, mode and state. The default pixmap-based engine stores any supplied file names, and it loads the pixmaps on demand instead of using scaled pixmaps if the size of a pixmap matches the size of icon requested. Custom icon engines that implement scalable vector formats are free to ignores any extra files.
