</brief_description>
<description>
- Represents one or many transformations in 2D space such as translation, rotation, or scaling. It consists of two [member x] and [member y] [Vector2]s and an [member origin]. It is similar to a 3×2 matrix.
+ 2×3 matrix (2 rows, 3 columns) used for 2D linear transformations. It can represent transformations such as translation, rotation, or scaling. It consists of a three [Vector2] values: [member x], [member y], and the [member origin].
