	  'scrollwheel' => FALSE,

line 178 insert:

$form['controls']['control_set']['scrollwheel'] = array(
    '#type' => 'radios',
    '#title' => t('Scroll wheel zoom'),
    '#options' => array(
      t('Disabled'),
      t('Enabled'),
    ),
    '#default_value' => (integer) $edit['settings']['scrollwheel'],
    '#description' => t('Allow the mouse wheel to zoom.'),
  );
