/** |

|
* Implements a DropShadow for components. In general, the DropShadowBorder will work with any rectangular components |
|
|
|
|
* that do not have a default border installed as part of the look and feel, or otherwise. For example, DropShadowBorder |
|
|
|
|
* works wonderfully with JPanel, but horribly with JComboBox. |
|
|
|
|
* <p> |
|
|
|
|
* Note: {@code DropShadowBorder} should usually be added to non-opaque components, otherwise the background is likely |
|
|
|
|
* to bleed through.</p> |
|

|
|
|
|
* between different instances of the class. Since this cache is shared at class level and never reset, it might bleed |
|
|
|
|
