/**

* Panel con los 3 campos para introducir listas de valores RGB. Este
|
| 16 |
* gestiona los eventos de FocusListener para validar que los valores
|
| 17 |
* que se introducen son correctos. Si el TextField pierde el foco y
|
| 18 |
* tiene un valor incorrecto resetea el contenido.
|
| 19 |
*
|
| 20 |
* Los m?todos publicos getRangeXXX devuelven el intervalo de valores
|
| 21 |
* en forma de array multidimensional de 2xN elementos. Cada pareja de
|
| 22 |
* valores es un rango de color en ese valor de pixel. Un rango de valores
|
| 23 |
* podria ser por ejemplo {{1,3},{15,30},{200, 255}}
