EXAMPLES
       Example #1

	      Object oriented style

	      <?php

	      $surface = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);

	      $context = new CairoContext($surface);

	      var_dump($context->clipExtents());
	      ?>

	      The above example will output something similar to:

	      array(4) {
		[0]=>
		float(0)
		[1]=>
		float(0)
		[2]=>

	      }

       Example #2

	      Procedural style

	      <?php

	      $surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);

	      $context = cairo_create($surface);

	      var_dump(cairo_clip_extents($context));

	      ?>

	      The above example will output something similar to:

	      array(4) {
		[0]=>
		float(0)
		[1]=>
		float(0)
		[2]=>
		float(50)
		[3]=>
