/*\
 * 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:
 | "t100,100r30,100,100s2,2,100,100r45s1.5"
 * 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.
 > Usage
 | var el = paper.rect(10, 20, 300, 200);
 | // translate 100, 100, rotate 45°, translate -100, 0
 | el.transform("t100,100r45t-100,0");
 | // if you want you can append or prepend transformations
 | el.transform("...t50,50");
 | el.transform("s2...");
 | // or even wrap
 | el.transform("t50,50...t-50-50");
 | // to reset transformation call method with empty string
 | el.transform("");
 | // to get current value call it without parameters
 | console.log(el.transform());

 * This method fixes the issue.

   Special thanks to Mariusz Nowak (http://www.medikoo.com/) for this method.
