## Create a new figure window for applications.
##
## Multiple property-value pairs may be specified for the figure object, but
## they must occur in pairs.
##
## The return value @var{h} is a graphics handle to the created figure object.
##
## Programming Note: The full list of properties is documented at
## @ref{Figure Properties}. This function differs from @code{figure} in that
## the created figure is optimized for application development, rather than
## plotting. This means features such as menubars and toolbars are turned off.
## This is not perfect replacement for the @sc{matlab} uifigure object as the
## properties @qcode{"AutoResizeChildren"}, @qcode{"Icon"}, and
## @qcode{"Scrollable"} are not implemented.
## @seealso{uipanel, uibuttongroup}
