this.dispatch('mouseMove', {x: e_pos_x,y: e_pos_y });
   
//Exact mouse position
const mouse_pos_x = e_pos_x * ( this.precanvas.clientWidth / (this.precanvas.clientWidth * this.zoom)) - (this.precanvas.getBoundingClientRect().x *  ( this.precanvas.clientWidth / (this.precanvas.clientWidth * this.zoom)) );

this.dispatch('mouseMoveExact', {x: mouse_pos_x,y: mouse_pos_y });
