-DESCRIPTION
-----------
-
-``gtk4-path-tool`` can perform various tasks on paths. Paths are specified
-in SVG syntax, as strings like "M 100 100 C 100 200 200 200 200 100 Z".
-
-To read a path from a file, use a filename that starts with a '.' or a '/'.
-To read a path from stdin, use '-'.
-
-COMMANDS
--------
-
-Stroking
-^^^^^^^^
-
-The ``stroke`` command performs a stroke operation along the path according to
-the parameters specified via options.
-
-``--line-width=VALUE``
-
-  The line width to use for the stroke. ``VALUE`` must be a positive number.
-  The default line width is 1.
-
-``--line-cap=VALUE``
-
-  The cap style to use at line ends. The possible values are ``butt``, ``round``
-  or ``square``. See the SVG specification for details on these styles.
-  The default cap style is ``butt``.
-
-``--line-join=VALUE``
-
-  The join style to use at line joins. The possible values are ``miter``,
-  ``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
-  for details on these styles.
-  The default join style is ``miter``.
-
-``--miter-limit=VALUE``
-
-  The limit at which to clip miters at line joins. The default value is 4.
-
-``--dashes=VALUE``
-
-  The dash pattern to use for this stroke. A dash pattern is specified by
-  a comma-separated list of alternating non-negative numbers. Each number
-  provides the length of alternate "on" and "off" portions of the stroke.
-  If the dash pattern is empty, dashing is disabled, which is the default.
-  See the SVG specification for details on dashing.
-
-``--dash-offset=VALUE``
-
-  The offset into the dash pattern where dashing should begin.
-  The default value is 0.
-
-Offsetting
-^^^^^^^^^^
-
-The ``offset`` command applies a lateral offset to the path. Note that this
-is different from applying a translation transformation.
-
-``--distance=VALUE``
-
-  The distance by which to offset the path. Positive values offset to the right,
-  negative values to the left (wrt to the direction of the path). The default
-  value is 0.
-
-``--line-join=VALUE``
-
-  The join style to use at line joins. The possible values are ``miter``,
-  ``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
-  for details on these styles.
-  The default join style is ``miter``.
-
-``--miter-limit=VALUE``
-
-  The limit at which to clip miters at line joins. The default value is 4.
-
-Boolean Operations
-^^^^^^^^^^^^^^^^^^
-
-The ``intersection``, ``union``, ``difference`` and ``symmetric-difference`` commands
-perform boolean operations on paths. Given two paths, they create a new path which
-encircles the area that is the intersection, union, difference or symmetric difference
-of the areas encircled by the paths.
-
-Simplification
-^^^^^^^^^^^^^^
-
-The ``simplify`` command removes areas of overlap from a path such that the resulting
-path encircles the same area, but every edge in the resulting path is a boundary between
-the inside and the outside.
-
-Decomposing
-^^^^^^^^^^^
-
-The ``decompose`` command approximates the path by one with simpler elements.
-When used without options, the curves of the path are approximated by line
-segments.
-
-``--allow-curves``
-
-  Allow cubic Bézier curves to be used in the generated path.
-
-``--allow-conics``
-
-  Allow rational quadratic Bézier curves to be used in the generated path.
-
-Restricting
-^^^^^^^^^^^
-
-The ``restrict`` command creates a path that traces a segment of the original
-path. Note that the start and the end of the segment are specified as
-path length from the beginning of the path.
-
-``--start=LENGTH``
-
-  The distance from the beginning of the path where the segment begins. The
-  default values is 0.
-
-``--end=LENGTH``
-
-  The distance from the beginning of the path where the segment ends. The
-  default value is the length of path.
-
-Showing
-^^^^^^^
-
-The ``show`` command displays the given path in a window. The interior
-of the path is filled.
-
-``--fill-rule=VALUE``
-
-  The fill rule that is used to determine what areas are inside the path.
-  The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
-
-``--fg-color=COLOR``
-
-  The color that is used to fill the interior of the path.
-  If not specified, black is used.
-
-``--bg-color=COLOR``
-
-  The color that is used to render the background behind the path.
-  If not specified, white is used.
-
-Rendering
-^^^^^^^^^
-
-The ``render`` command renders the given path as a PNG image.
-The interior of the path is filled.
-
-``--fill-rule=VALUE``
-
-  The fill rule that is used to determine what areas are inside the path.
-  The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
-
-``--fg-color=COLOR``
-
-  The color that is used to fill the interior of the path.
-  If not specified, black is used.
-
-``--bg-color=COLOR``
-
-  The color that is used to render the background behind the path.
-  If not specified, white is used.
-
-``--output-file=FILE``
-
-  The file to save the PNG image to.
-  If not specified, "path.png" is used.
-
-Info
-^^^^
-
-The ``info`` command shows various information about the given path,
-such as the number of contours, its bounding box and and its length.

-
-   "Approximation of circular arcs by cubic polynomials", Michael
-   Goldapp, Computer Aided Geometric Design 8 (1991) 227-238, provides

-
-   From that paper, a very practical value of h is:
-
-        h = 4/3 * R * tan(angle/4)
-
-   This value does not give the spline with minimal error, but it does
-   provide a very good approximation, (6th-order convergence), and the
-   error expression is quite simple, (see the comment for
