    Summary description: Lua-based mathematical graphs for LuaLaTeX

    Announcement text: ----------------------------------------------------------------------


    Added methods for drawing on a plane in space using 2D graphics methods.

    Added vector fields tangent to a surface in the *luadraw_fields* module.

    Added stereographic projection of a spherical facets or of circles in the *luadraw_spherical* module.

    Bug fixes...

    * The *luadraw_pdfliteral* module has been added; it allows
    for direct drawing within the PDF stream rCo including 2D paths,
    2D polylines, sets of 2D points (circular), or 3D facets rCo
    without using the \draw command. This significantly reduces
    compilation time when dealing with large datasets, subject
    to certain limitations.

    * Bug fixes...

    Addition of functions specific to 2D or 3D paths (conversions).
    For the method *g:Beginclip(path, inverse)*, the *path* can be
    a 2D or 3D path.

    Addition of methods returning the characteristic elements of
    cylinders, cones, truncated cones, and spheres (outline, visible
    edge, hidden edge, tangency points, etc.).

    In the *luadraw_spherical* module: addition of the *g:DSregion()* method.
