//| ==========================================================================
//|
//| Represents any shape made by defining boundaries that may be mirrored.

//| .. class:: Shape(width, height, *, mirror_x=False, mirrored_y=False)

//|   Create a Shape object with the given fixed size. Each pixel is one bit and is stored by the

//|   :param int width: The number of pixels wide
//|   :param int height: The number of pixels high
//|   :param bool mirror_x: When true the left boundary is mirrored to the right.
//|   :param bool mirror_y: When true the top boundary is mirrored to the bottom.
