/**
|
||||
* GskPathBuilder:
|
||||
*
|
||||
* A `GskPathBuilder` is an auxiliary object that is used to
|
||||
* create new `GskPath` objects.
|
||||
*
|
||||
* A path is constructed like this:
|
||||
*
|
||||
* ```
|
||||
* GskPath *
|
||||
* construct_path (void)
|
||||
* {
|
||||
* GskPathBuilder *builder;
|
||||
*
|
||||
* builder = gsk_path_builder_new ();
|
||||
*
|
||||
* // add contours to the path here
|
||||
*
|
||||
* return gsk_path_builder_free_to_path (builder);
|
||||
* }
|
||||
* ```
|
||||
*
|
||||
* Adding contours to the path can be done in two ways.
|
||||
* The easiest option is to use the `gsk_path_builder_add_*` group
|
||||
* of functions that add predefined contours to the current path,
|
||||
* either common shapes like [method@Gsk.PathBuilder.add_circle]
|
||||
* or by adding from other paths like [method@Gsk.PathBuilder.add_path].
|
||||
*
|
||||
* The other option is to define each line and curve manually with
|
||||
* the `gsk_path_builder_*_to` group of functions. You start with
|
||||
* a call to [method@Gsk.PathBuilder.move_to] to set the starting point
|
||||
* and then use multiple calls to any of the drawing functions to
|
||||
* move the pen along the plane. Once you are done, you can call
|
||||
* [method@Gsk.PathBuilder.close] to close the path by connecting it
|
||||
* back with a line to the starting point.
|
||||
* This is similar for how paths are drawn in Cairo.

that the spline control points must be:

"Approximation of circular arcs by cubic polynomials", Michael

Goldapp, Computer Aided Geometric Design 8 (1991) 227-238, provides

various values of h along with error analysis for each.

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
