-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.

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