Description:
------------
imagefilltoborder stops filling a polygon before reaching
all the borders.
The code provided works as expected with php 4.3.4. 
Not tested with 4.3.5


Reproduce code:
---------------
header("Content-type: image/png");
$id = @imagecreate(200, 200);

$background_color = imagecolorallocate($id, 0, 0, 0);
$color = imagecolorallocate($id, 255, 0, 0);
$contorno = imagecolorallocate($id, 0, 255, 0);

$puntos = array(135,22,138,22,138,29,158,29,158,49,136,49,136,41,132,41,132,33,135,33,135,22);

imagepolygon($id, &$puntos, floor(count($puntos)/2), $contorno);
imagefilltoborder($id, 145, 35, $contorno, $color);

ImagePng( $id );
ImageDestroy( $id );


Expected result:
----------------
A red filled green polygon

Actual result:
--------------
A partially red filled green polygon
