     * Element.transform
     [ method ]
     **
     * Adds transformation to the element which is separate to other attributes,
     * i.e. translation doesn’t change `x` or `y` of the rectange. The format
     * of transformation string is similar to the path string syntax:
     | &quot;t100,100r30,100,100s2,2,100,100r45s1.5&quot;
     * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
     * scale and `m` is for matrix.
     *
     * There are also alternative “absolute” translation, rotation and scale: `T`, `R` and `S`. They will not take previous transformation into account. For example, `...T100,0` will always move element 100 px horisontally, while `...t100,0` could move it vertically if there is `r90` before. Just compare results of `r90t100,0` and `r90T100,0`.
     *
     * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
     * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
     * coordinates as optional parameters, the default is the centre point of the element.
     * Matrix accepts six parameters.
     &gt; Usage
     | var el = paper.rect(10, 20, 300, 200);
     | // translate 100, 100, rotate 45°, translate -100, 0
     | el.transform(&quot;t100,100r45t-100,0&quot;);
     | // if you want you can append or prepend transformations
     | el.transform(&quot;...t50,50&quot;);
     | el.transform(&quot;s2...&quot;);
     | // or even wrap

     | // to reset transformation call method with empty string
