 *
 * A base control for creating gallery chooser control. Based on the WordPress
 * media library galleries. Used to select images from the WordPress media library.
 *
 * Creating new control in the editor (inside `Widget_Base::_register_controls()`
 * method):
 *
 *    $this->add_control(
 *    	'gallery',
 *    	[
 *    		'label' => __( 'Add Images', 'plugin-domain' ),
 *    		'type' => Controls_Manager::GALLERY,
 *    		'default' => [],
 *    	]
 *    );
 *
 * PHP usage (inside `Widget_Base::render()` method):
 *
 *    $images = $this->get_settings( 'gallery' );
 *    foreach ( $images as $image ) {
 *    	echo '<img src="' . $image['url'] . '">';
 *    }
 *
 * JS usage (inside `Widget_Base::_content_template()` method):
 *
 *    <# _.each( settings.gallery, function( image ) { #>
 *    	<img src="{{ image.url }}">
 *    <# }); #>
