  6292. | "t100,100r30,100,100s2,2,100,100r45s1.5"
  6293. * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
  6294. * scale and `m` is for matrix.
  6295. *
  6296. * 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`.
  6297. *
  6298. * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
  6299. * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin

  6478. * gradient from white to black or “`0-#fff-#f00:20-#000`” – 0° gradient from white via red (at 20%) to black.
  6479. *
  6480. * radial gradient: “`r[(‹fx›, ‹fy›)]‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`r#fff-#000`” –
  6481. * gradient from white to black or “`r(0.25, 0.75)#fff-#000`” – gradient from white to black with focus point
  6482. * at 0.25, 0.75. Focus point coordinates are in 0..1 range. Radial gradients can only be applied to circles and ellipses.
