\brief The QPlaceIcon class represents an icon.
The typical usage of an icon is to use the url() function to specify
a preferred icon size.
\snippet places/requesthandler.h icon
The icons are typically backend dependent, if a manager backend does not support a given size, the URL of the icon that most
closely matches those parameters is returned.
The icon class also has a key-value set of parameters. The precise key one
needs to use depends on the \l {Qt Location#Plugin References and Parameters}{plugin}
being used. These parameters influence which icon URL is returned by
the manager and may also be used to specify icon URL locations when
saving icons.
If there is only ever one image for an icon, then QPlaceIcon::SingleUrl can be used as a parameter
key with a QUrl as the associated value. If this key is set, then the url() function will always return the specified URL
and not defer to any manager.
