<description>
Creates an [Array] of polygons covering a rectangular portion of the bitmap. It uses a marching squares algorithm, followed by Ramer-Douglas-Peucker (RDP) reduction of the number of vertices. Each polygon is described as a [PackedVector2Array] of its vertices.
To get polygons covering the whole bitmap, pass:
[codeblock]
Rect2(Vector2(), get_size())
[/codeblock]
[code]epsilon[/code] is passed to RDP to control how accurately the polygons cover the bitmap: a lower [code]epsilon[/code] corresponds to more points in the polygons.
