The Transformation from Object to World coordinates (normally logic coordinates).

The Transformation from World to View coordinates (normally logic coordinates
to discrete units, e.g. pixels).
@param rViewport
The visible part of the view in World coordinates. If empty (getViewport().isEmpty())
everything is visible. The data is in World coordinates.
@param rxDrawPage
The currently displaqyed page. This information is needed e.g. due to existing PageNumber
fields which need to be interpreted.

The time the view is defined for. Default is 0.0. This parameter is used e.g. for
animated objects

A sequence of property values which allows holding various other parameters besides
the obvious and needed ones above. For this constructor none of the other parameters
should be added as data. The constructor will parse the given parameters and if
data for the other parameters is given, the value in rExtendedParameters will
be preferred and overwrite the given parameter
