<brief_description>
A navigation polygon that defines traversable areas and obstacles.
A 2D navigation mesh that describes a traversable surface for pathfinding.
</brief_description>
<description>
There are two ways to create polygons. Either by using the [method add_outline] method, or using the [method add_polygon] method.
Using [method add_outline]:
A navigation mesh can be created either by baking it with the help of the [NavigationServer2D], or by adding vertices and convex polygon indices arrays manually.
To bake a navigation mesh at least one outline needs to be added that defines the outer bounds of the baked area.

Parses the [SceneTree] for source geometry according to the properties of [param navigation_polygon]. Updates the provided [param source_geometry_data] resource with the resulting data. The resource can then be used to bake a navigation mesh with [method bake_from_source_geometry_data]. After the process is finished the optional [param callback] will be called.
[b]Note:[/b] This function needs to run on the main thread or with a deferred call as the SceneTree is not thread-safe.
[b]Performance:[/b] While convenient, reading data arrays from [Mesh] resources can affect the frame rate negatively. The data needs to be received from the GPU, stalling the [RenderingServer] in the process. For performance prefer the use of e.g. collision shapes or creating the data arrays entirely in code.
