* `size`: Size of the minimap to display. Minimap should be a square to avoid
distortion.
* Negative values represent percentages of the screen. If either `x` or `y`
is specified as a percentage, the resulting pixel size will be used for
both `x` and `y`. Example: On a 1920x1080 screen, `{x = 0, y = -25}` will
result in a 270x270 minimap.
* Negative values are supported starting with protocol version 45.
* `alignment`: The alignment of the minimap.
* `offset`: offset in pixels from position.
