   /*\
    * 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.
