 * ensure that `el` is the same or the same size & location as `e.target`.
 * Otherwise the result coords are probably not expected. Because we
 * firstly try to get coords from e.offsetX/e.offsetY.
 * + If `calculate` is set as `true`, the input `el` can be any element
 * and we force to calculate the coords based on `el`.
 * + The input `el` should be positionable (not position:static).
 *
 * The force `calculate` can be used in case like:
 * When mousemove event triggered on ec tooltip, `e.target` is not `el`(zr painter.dom).
 *
 * @param  el DOM element.
 * @param  e Mouse event or touch event.
 * @param  out Get `out.zrX` and `out.zrY` as the result.
