+     * 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`.

+     * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin

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