Resets the current transform to the identity matrix. Then runs transform()

@name setTransform
@function
@param a {Number} Horizontal scaling
@param b {Number} Horizontal skewing
@param c {Number} Vertical skewing
@param d {Number} Vertical scaling
@param e {Number} Horizontal moving
@param f {Number} Vertical moving
@description Each object on the canvas has a current transformation matrix. <br /><br />The setTransform() method resets the current transform to the identity matrix, and then runs transform() with the same arguments.<br /><br />In other words, the setTransform() method lets you scale, rotate, move, and skew the current context.
