Release of ezdxf v1.0.1

[mozman]

Release v1.0.1

Version v1.0.1 is a bugfix release, that also includes some minor new additions and an
important change in the way how SPLINE entities are created from fit points only.

Up to this version, the control-points calculated by ezdxf for SPLINE entities from fit-points only did not match the control-points calculated by CAD applications. After more than two years, Antonio Spagnuolo answered my question about how to get the same control-points as CAD applications on "stack overflow". The solution does not require an end tangent estimate, so the tangent estimate arguments have been removed from the associated methods and functions.

Changes

• NEW: function set_lineweight_display_style() in module ezdxf.appsettings
• NEW: function set_current_dimstyle_attribs() in module ezdxf.appsettings
• NEW: ezdxf info command shows unknown/unsupported entities in stats
• CHANGE: the function fit_points_to_cad_cv() can calculate the control points of
  B-splines from fit points like BricsCAD, the argument estimate is not necessary
  anymore and was removed
• CHANGE: removed argument estimate from factory method add_cad_spline_control_frame(), see above
• BUGFIX: fix LWPOLYLINE parsing in ProxyGraphic class, An issue on some MULTILEADER explosion #793
• BUGFIX: fix minimum axis-ratio for the ELLIPSE entity, added upperbound tolerance to axis-ratio validator to take floating point imprecision into account, ELLIPSE should accept an axis ratio as small as 1e-10 #800
• BUGFIX: fix function ezdxf.render.forms.cylinder_2p() for cylinder axis parallel to z-axis , cylinder_2p in negative z-direction #810
• BUGFIX: fix function ezdxf.render.forms.cone_2p() for cone axis parallel to z-axis, cone_2p ZeroDivisionError: float division #811
• BUGFIX: add support for multiple shape file entries in the TextstyleTable class
