For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

2D transformation (2×3 matrix).
|
||
</brief_description>
|
||
<description>
|
||
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 three [Vector2] values: [member x], [member y], and the [member origin].
