Pass a handwriting stroke to an input method engine.
In this API, a coordinate (0.0, 0.0) represents the top-left corner of an area for handwriting, and (1.0, 1.0) does the bottom-right. Therefore, for example, if a user writes a character 'L', the array would be something like [0.0, 0.0, 0.0, 1.0, 1.0, 1.0] and coordinates_len would be 6.
The function is usually called when a user releases the mouse button in a hand writing area.
