CameraFocus is part of the \b{QtMultimedia 5.0} module.
This type allows control over manual and automatic
focus settings, including information about any parts of the
camera frame that are selected for autofocusing.
It should not be constructed separately, instead the
\c focus property of a \l Camera should be used.
