/*\
* Paper.gradient
[ method ]
**
* Creates a gradient element
**
- gradient (string) gradient descriptor
> 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.
> Examples
* Linear gradient, relative from top-left corner to bottom-right
* corner, from black through red to white:
| var g = paper.gradient("l(0, 0, 1, 1)#000-#f00-#fff");
* Linear gradient, absolute from (0, 0) to (100, 100), from black
* through red at 25% to white:
| var g = paper.gradient("L(0, 0, 100, 100)#000-#f00:25-#fff");
* Radial gradient, relative from the center of the element with radius
* half the width, from black to white:
| var g = paper.gradient("r(0.5, 0.5, 0.5)#000-#fff");
* To apply the gradient:
| paper.circle(50, 50, 40).attr({
| fill: g
| });
