Address the speed of plotting large hggroup groups and in particular contours (bug #31305). Changes to address this include - Use __go_patch__ in __contour__ rather than patch so that the cost of setting up the callback functions is avoided. The contourgroup callback handles the updating of properties. - Add children_property class to store children in a list so that adding and deleting children is a low cost operation. - Create a new version of update_axis_limits code that doesn't force the recalculation of all of the objects children. Patch also allows unclosed patch contours with the FLTK backend.

There are binary packages for Debian, Fedora, and other GNU/Linux
distributions.

Octave should build cleanly from source on most GNU/Linux systems.
