+follows: <code>&lt;type&gt;(&lt;coords&gt;)&lt;colors&gt;</code>.  The <code>&lt;type&gt;</code> can be
+either linear or radial.  The uppercase <code>L</code> or <code>R</code> letters
+indicate absolute coordinates offset from the SVG surface.
+Lowercase <code>l</code> or <code>r</code> letters indicate coordinates
+calculated relative to the element to which the gradient is
+applied.  Coordinates specify a linear gradient vector as
+<code>x1</code>, <code>y1</code>, <code>x2</code>, <code>y2</code>, or a radial gradient as <code>cx</code>, <code>cy</code>,
+<code>r</code> and optional <code>fx</code>, <code>fy</code> specifying a focal point away
+from the center of the circle. Specify <code>&lt;colors&gt;</code> as a list
+of dash-separated CSS color values.  Each color may be
+followed by a custom offset value, separated with a colon
+character.
