/**

 * According to the gvSIG's GUI style sheet all the buttons in the application will

 * have a normative size. No smaller than a concrete size, and big enough to contain

 * the text and avoiding the "..." characters. The button will grow up in width by

 * a set of widths defined in this style sheet, always choosing the smallest width that

 * can contain the text. If the biggest width is not enought for this purpose then the

 * button will automatically grow up to the smallest necessary width to fit the text.<br>

 * <p>

 * The button resizing is based on the <b>setText(String txt)</b> method. However,

 * it is possible to use a custom size if you invoke one of <b>setSize(..)</b>,

 * <b>setBorders(...)</b> or <b>setPreferredSize(...)</b> after invoking the

 * <b>setText(...)<b> method.

 * <p>

 * This class is just a standard javax.swing.JButton that handles this issue.
