GradientBar

java.lang.Object
- java.awt.Component
- - java.awt.Container
  - - javax.swing.JComponent
    - - com.fr.design.style.background.gradient.GradientBar

所有已实现的接口:

UIObserver, ColorSelectable, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

直接已知子类:

FixedGradientBar
```
public class GradientBar
extends javax.swing.JComponent
implements UIObserver, ColorSelectable
```
TODO:面板缩放的功能没有考虑（就是尾值过大，导致超过界面显示的情况），原来的那个实现完全是个BUG。要缩放的情况也比较少，就干脆以后弄吧
