944 * Linear gradient format: “`‹angle›-‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`90-#fff-#000`” – 90°
945 * gradient from white to black or “`0-#fff-#f00:20-#000`” – 0° gradient from white via red (at 20%) to black.
947 * radial gradient: “`r[(‹fx›, ‹fy›)]‹colour›[-‹colour›[:‹offset›]]*-‹colour›`”, example: “`r#fff-#000`” –
948 * gradient from white to black or “`r(0.25, 0.75)#fff-#000`” – gradient from white to black with focus point
949 * at 0.25, 0.75. Focus point coordinates are in 0..1 range. Radial gradients can only be applied to circles and ellipses.
