  6468. * of transformation string is similar to the path string syntax:
  6469. | "t100,100r30,100,100s2,2,100,100r45s1.5"
  6470. * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
  6471. * scale and `m` is for matrix.
  6472. *
  6473. * 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`.
  6474. *
  6475. * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
  6476. * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
  6477. * coordinates as optional parameters, the default is the centre point of the element.
