Move form elements into fieldsets for presentation purposes.
Many views forms use #tree = TRUE to keep their values in a hierarchy for easier storage. Moving the form elements into fieldsets during form building would break up that hierarchy. Therefore, we wait until the pre_render stage, where any changes we make affect presentation only and aren't reflected in $form_state['values'].

// to any element that belongs in a fieldset. If this form element has that
// property, move it into its fieldset.
if (isset($element['#fieldset']) && isset($form[$element['#fieldset']])) {
$form[$element['#fieldset']][$key] = $element;
// Remove the original element this duplicates.
unset($form[$key]);
