* The Gravity attribute (integer) specifies the default way the field aligns itself when displayed in a matrix field cell. Gravity is translated to the equivalent anchor value in a {@link GridBagContstraint}.
* Gravity accepts the following values:
* <li>Constants.CG_BOTTOMCENTER Bottom of the cell, centered horizontally.</li>
* <li>Constants.CG_BOTTOMLEFT Bottom, left corner of the cell.</li>
* <li>Constants.CG_BOTTOMRIGHT Bottom, right corner of the cell.</li>
* <li>Constants.CG_CENTER Center of the cell.</li>
* <li>Constants.CG_DEFAULT Same as CG_CENTER.</li>
* <li>Constants.CG_MIDDLELEFT Left side of the cell, centered vertically.</li>
* <li>Constants.CG_MIDDLERIGHT Right side of the cell, centered vertically.</li>
* <li>Constants.CG_TOPCENTER Top of the cell, centered horizontally.</li>
* <li>Constants.CG_TOPLEFT Top, left corner of the cell.</li>
* <li>Constants.CG_TOPRIGHT Top, right corner of the cell.</li>
