A Polygon2D is defined by a set of n vertices connected together by line segments, meaning that the vertex 1 will be connected with vertex 2, vertex 2 with vertex 3 ..., vertex n-1 with vertex n and vertex n with vertex 1 in order to close the loop and define a polygon.
Set the polygon fill color. If the polygon has a texture defined, the defined texture will be multiplied by the polygon fill color. This, also, is the default color for those vertices that are not defined by [method get_vertex_colors].

Set the polygon as the defined polygon bounding box minus the defined polygon (the defined polygon will appear as a hole on the square that contains the defined polygon).
Add extra padding around the bounding box, making it bigger. Too small a value can make the polygon triangulate strangely, due to numerical imprecision.

Set the an offset that will be added to the vertices' position. E.g. if the offset is set to (10,10) then all the polygon points will move 10 units to the right and 10 units to the bottom.
Set the offset of the polygon texture. Initially the texture will appear anchored to the polygon position, the offset is used to move the texture location away from that point (notice that the texture origin is set to its top left corner, so when offset is 0,0 the top left corner of the texture is at the polygon position), for example setting the offset to 10, 10 will move the texture 10 units to the left and 10 units to the top.
Set the value that will multiply the uv coordinates ([method get_uv]) when applying the texture. Larger values make the texture smaller, and vice versa.
Set the texture coordinates for every vertex of the polygon. There should be one uv vertex for every vertex in the polygon. If there are less, the undefined ones will be assumed to be (0,0). Extra uv vertices are ignored.
Set the color for each vertex of the polygon. There should be one color for every vertex in the polygon. If there are less, the undefined ones will be assumed to be [method get_color]. Extra color entries are ignored.
Colors are interpolated between vertices, resulting in smooth gradients when they differ.
