• Path - A `GskPath` describes lines and curves that are more complex than simple rectangles.
• PathBuilder - `GskPathBuilder` is an auxiliary object for constructing `GskPath` objects.
• PathMeasure - `GskPathMeasure` is an object that allows measurements on `GskPath`s such as determining the length of the path.
• PathPoint - `GskPathPoint` is an opaque type representing a point on a path.
• RadialGradientNode - A render node for a radial gradient.

• ShadowNode - A render node drawing one or more shadows behind its single child node.
• Stroke - A `GskStroke` struct collects the parameters that influence the operation of stroking a path.
• StrokeNode - A render node that will fill the area determined by stroking the the given [struct@Gsk.

Structs:

• ColorStop - A color stop in a gradient node.
• ParseLocation - A location in a parse buffer.
• RoundedRect - A rectangular region with rounded corners.
• Shadow - The shadow parameters in a shadow node.

Enums:

• BlendMode - The blend modes available for render nodes.
• Corner - The corner indices used by `GskRoundedRect`.
• FillRule - `GskFillRule` is used to select how paths are filled.
• GLUniformType - This defines the types of the uniforms that `GskGLShaders` declare.
• LineCap - Specifies how to render the start and end points of contours or dashes when stroking.
• LineJoin - Specifies how to render the junction of two lines when stroking.
• MaskMode - The mask modes available for mask nodes.
• PathDirection - The values of the `GskPathDirection` enum are used to pick one of the four tangents at a given point on the path.
• PathForeachFlags - Flags that can be passed to @foreach to influence what kinds of operations the path is decomposed into.
• PathOperation - Path operations are used to describe the segments of a `GskPath`.
• RenderNodeType - The type of a node determines what the node is rendering.
• ScalingFilter - The filters used when scaling texture data.
• TransformCategory - The categories of matrices relevant for GSK and GTK.

Error domains:

• SerializationError - Errors that can happen during (de)serialization.

Delegates:

• public delegate void ParseErrorFunc (ParseLocation start, ParseLocation end) throws Error
  Type of callback that is called when an error occurs during node deserialization.
• public delegate bool PathForeachFunc (PathOperation op, Point pts, size_t n_pts, float weight)
  Prototype of the callback to iterate through the operations of a path.

Functions:

• public Path? path_parse (string string)
  This is a convenience function that constructs a `GskPath` from a serialized form.
• public Quark serialization_error_quark ()
• public bool stroke_equal (void* stroke1, void* stroke2)
  Checks if 2 strokes are identical.
• public bool transform_parse (string string, out Transform out_transform)
  Parses the given string into a transform and puts it in out_transform.
• public RenderNode? value_dup_render_node (Value value)
  Retrieves the `GskRenderNode` stored inside the given `value`, and acquires a reference to it.
• public unowned RenderNode? value_get_render_node (ref Value value)
  Retrieves the `GskRenderNode` stored inside the given `value`.
• public void value_set_render_node (ref Value value, RenderNode node)
