Update figure graphics object for Matlab compatibility.
* NEWS.8.md: Announce addition of "innerposition" and "windowstate" properties
to figure objects. Announce change in default for "dockcontrols" property to
"on".
* graphics.in.h (figure::properties::get_innerposition,
figure::properties::set_innerposition): New functions to alias "innerposition"
property to "position" property.
* graphics.in.h (BEGIN_PROPERTIES (figure)): Change "dockcontrols" default to
"on". Re-order "pointer" property to show the default "arrow" as the first
entry. Add new property "windowstate".
