 Once you have all the necessary dependencies, you can build GTK by using
 Meson:
 
 ```sh
-$ meson setup _build
-$ meson compile -C_build
+$ meson _build .
+$ cd _build
+$ ninja
 ```
 
 You can run the test suite using:
 
 ```sh
-$ meson test -C_build
+$ meson test
 ```
 
 And, finally, you can install GTK using:
 
 ```
-$ sudo meson install -C_build
+$ sudo ninja install
 ```

-Title: Paths
-Slug: paths
-
-GSK provides a path API that can be used to render more complex
-shapes than lines or rounded rectangles. It is comparable to cairos
-[path API](https://www.cairographics.org/manual/cairo-Paths.html),
-with some notable differences.
-
-In general, a path consists of one or more connected **_contours_**,
-each of which may have multiple **_operations_**, and may or may not be closed.
-Operations can be straight lines or curves of various kinds. At the points
-where the operations connect, the path can have sharp turns.
-
-<figure>
-  <picture>
-    <source srcset="path-dark.png" media="(prefers-color-scheme: dark)">
-    <img alt="A path with multiple contours" src="path-light.png">
-  </picture>
-  <figcaption>A path with one closed, and one open contour</figcaption>
-</figure>
-
-The central object of the GSK path API is the immutable [struct@Gsk.Path]
-struct, which contains path data in compact form suitable for rendering.
-
-## Creating Paths
-
-Since `GskPath` is immutable, the auxiliary [struct@Gsk.PathBuilder] struct
-can be used to construct a path piece by piece. The pieces are specified with
-points, some of which will be on the path, while others are just **_control points_**
-that are used to influence the shape of the resulting path.
-
-<figure>
-  <picture>
-    <source srcset="cubic-dark.png" media="(prefers-color-scheme: dark)">
-    <img alt="An cubic Bézier" src="cubic-light.png">
-  </picture>
-  <figcaption>A cubic Bézier operation, with 2 control points</figcaption>
-</figure>
-
-The `GskPathBuilder` API has three distinct groups of functions:
-
-- Functions for building contours from individual operations, like [method@Gsk.PathBuilder.move_to],
-  [method@Gsk.PathBuilder.line_to], [method@Gsk.PathBuilder.cubic_to], [method@Gsk.PathBuilder.close]. `GskPathBuilder` maintains a **_current point_**, so these methods all
-  take one less points than necessary for the operation (e.g. `gsk_path_builder_line_to`
-  only takes a single point and draws a line from the current point to the new point).
-
-- Functions for adding complete contours, such as [method@Gsk.PathBuilder.add_rect],
-  [method@Gsk.PathBuilder.add_rounded_rect], [method@Gsk.PathBuilder.add_circle].
-
-- Adding parts of a preexisting path. Functions in this group include
-  [method@Gsk.PathBuilder.add_path] and [method@Gsk.PathBuilder.add_segment].
-
-When you are done with building a path, you can convert the accumulated path
-data into a `GskPath` struct with [method@Gsk.PathBuilder.free_to_path].
-
-A sometimes convenient alternative is to create a path from a serialized form,
-with [func@Gsk.Path.parse]. This function interprets strings in SVG path syntax,
-such as:
-
-    M 100 100 C 100 200 200 200 200 100 Z
-
-## Rendering with Paths
-
-There are two main ways to render with paths. The first is to **_fill_** the
-interior of a path with a color or more complex content, such as a gradient.
-GSK supports different ways of determining what part of the plane are interior
-to the path, which can be selected with a [enum@Gsk.FillRule] value.
-

-    <img alt="A filled path" src="fill-even-odd.png">
-  </picture>
-  <figcaption>The same path, filled with GSK_FILL_RULE_EVEN_ODD</figcaption>
-</figure>
-
-To fill a path, use [gtk_snapshot_append_fill()](../gtk4/method.Snapshot.append_fill.html)
-or the more general [gtk_snapshot_push_fill()](../gtk4/method.Snapshot.push_fill.html).
-
-Alternatively, a path can be **_stroked_**, which means to emulate drawing
-with an idealized pen along the path. The result of stroking a path is another
-path (the **_stroke path_**), which is then filled.
-
-The stroke operation can be influenced with the [struct@Gsk.Stroke] struct
-that collects various stroke parameters, such as the line width, the style
-of line joins and line caps, and a dash pattern.
-

-    <img alt="A stroked path" src="stroke-round.png">
-  </picture>
-  <figcaption>The same path, stroked with GSK_LINE_JOIN_ROUND</figcaption>
-</figure>
-
-To stroke a path, use
-[gtk_snapshot_append_stroke()](../gtk4/method.Snapshot.append_stroke.html)
-or [gtk_snapshot_push_stroke()](../gtk4/method.Snapshot.push_stroke.html).
-
-## Hit testing
-
-When paths are rendered as part of an interactive interface, it is sometimes
-necessary to determine whether the mouse points is over the path. GSK provides
-[method@Gsk.Path.in_fill] for this purpose.
-
-## Path length
-
-An important property of paths is their **_length_**. Computing it efficiently
-requires caching, therefore GSK provides a separate [struct@Gsk.PathMeasure] object
-to deal with path lengths. After constructing a `GskPathMeasure` object for a path,
-it can be used to determine the length of the path with [method@Gsk.PathMeasure.get_length]
-and locate points at a given distance into the path with [method@Gsk.PathMeasure.get_point].
-
-## Other Path APIs
-
-Paths have uses beyond rendering, for example as trajectories in animations.
-In such uses, it is often important to access properties of paths, such as
-their tangents at certain points. GSK provides an abstract representation
-for points on a path in the form of the [struct@Gsk.PathPoint] struct.
-You can query properties of a path at certain point once you have a
-`GskPathPoint` representing that point.
-
-`GskPathPoint` structs can be compared for equality with [method@Gsk.PathPoint.equal]
-and ordered wrt. to which one comes first, using [method@Gsk.PathPoint.compare].
-
-To obtain a `GskPathPoint`, use [method@Gsk.Path.get_closest_point],
-[method@Gsk.Path.get_start_point], [method@Gsk.Path.get_end_point] or
-[method@Gsk.PathMeasure.get_point].
-
-To query properties of the path at a point, use [method@Gsk.PathPoint.get_position],
-[method@Gsk.PathPoint.get_tangent], [method@Gsk.PathPoint.get_rotation],
-[method@Gsk.PathPoint.get_curvature] and [method@Gsk.PathPoint.get_distance].
-
-Some of the properties can have different values for the path going into
-the point and the path leaving the point, typically at points where the
-path takes sharp turns. Examples for this are tangents (which can have up
-to 4 different values) and curvatures (which can have two different values).

-## Going beyond GskPath
-
-Lots of powerful functionality can be implemented for paths:
-
-- Finding intersections
-- Offsetting curves
-- Turning stroke outlines into paths
-- Molding curves (making them pass through a given point)
-
-GSK does not provide API for all of these, but it does offer a way to get at
-the underlying Bézier curves, so you can implement such functionality yourself.
-You can use [method@Gsk.Path.foreach] to iterate over the operations of the
-path, and get the points needed to reconstruct or modify the path piece by piece.
-
-See e.g. the [Primer on Bézier curves](https://pomax.github.io/bezierinfo/)
-for inspiration of useful things to explore.
