Gradient (Charba - J2CL and GWT charts library based on CHART.JS)

java.lang.Object
- org.pepstock.charba.client.commons.NativeObjectContainer
- - org.pepstock.charba.client.colors.CanvasObject
  - - org.pepstock.charba.client.colors.Gradient

```
public final class Gradient
extends CanvasObject
```
A gradient is an image consisting of a progressive transition between two or more colors.
Could be Linear or Radial.
Can be created using the size of CANVAS or CHART area.
The orientation to have a progressive transition, is defined by an enumeration in order to creates the gradient using the right coordinates and dimension, based on existing items (canvas and chart).
