= (function) returned function accepts a single numeric parameter that represents z-index of the handler. It is an optional feature and only used when you need to ensure that some subset of handlers will be invoked in a given order, despite of the order of assignment.

> Example:
|

| eve.on("mouse", eatIt)(2);
|
||
| eve.on("mouse", scream);
|

| eve.on("mouse", catchIt)(1);
|

|
||
*
|
||
* If you want to put your handler before non-indexed handlers, specify a negative value.

* 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
|

* corner, from black through red to white:

||
* 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({
