Image sizes not integers

When using wp_get_attachment_image() to include an image, the width and height were outputting as float values rather than integers.

I’ve got around this by adding the following filter to my functions:

function fix_direct_image_output($attr) {
	if(isset($attr['height'])) {
		$attr['height'] = intval($attr['height']);
	}

	if(isset($attr['width'])) {
		$attr['width'] = intval($attr['width']);
	}

	return $attr;
}
add_filter( 'wp_get_attachment_image_attributes', 'fix_direct_image_output', 11, 1 );

I’m not sure if fractional sizes were intentional or not but the W3C validator was reporting it as an error.
