shar file for new port graphics/py-visvis

Visvis[1] is a pure Python library for visualization of 1D to 4D data in an
object oriented way. Essentially, visvis is an object oriented layer of Python
on top of OpenGl, thereby combining the power of OpenGl with the usability of
Python. A Matlab-like interface in the form of a set of functions allows easy
creation of objects (e.g. plot(), imshow(), volshow(), surf()).

With visvis a range of different data can be visualized by simply adding world
objects to a scene (or axes). These world objects can be anything from plots
(lines with markers), to images, 3D rendered volumes, shaded meshes, or you can
program your own world object class. If required, these data can also be moved
in time.


The port is needed as a dependency for plugins (i.e. RasterTool[2]) of
graphics/qgis[3].

The patch is tested on Poudriere (11.3i/a, 12.0i/a, and HEADi/a),
'portlint -AC' seems happy.
