<description>
Applies morphological dilation or erosion to the bitmap. If [param pixels] is positive, dilation is applied to the bitmap. If [param pixels] is negative, erosion is applied to the bitmap. [param rect] defines the area where the morphological operation is applied. Pixels located outside the [param rect] are unaffected by [method grow_mask].

<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.
