Bug description:angles parameters in imagefilledarc are integers, they should be float

Description:
------------
see sample result at
http://mon-convertisseur.fr/php/imgangle.php?DEGRE=172.3

angles are truncated to nearest integer, in imagefilledarc function, they
shouldn't

you can change parameter if you like

---
From manual page:
http://www.php.net/function.imagefilledarc#refsect1-function.imagefilledarc-description
---



Test script:
---------------
header("Content-type: image/jpeg");

if (isset($_GET["DEGRE"])){ $lDegre=$_GET["DEGRE"];}
$lSizeX=916;
$lSizeY=945;
$image  = imagecreatetruecolor($lSizeX, $lSizeY);
$colorGreen = imagecolorallocate($image, 0, 255, 0);
		
// background coming from
http://commons.wikimedia.org/wiki/File:Protractor_katomierz.jpg
with some
little changes
$fond=imagecreatefromjpeg("Protractor_katomierz_tourne05b.jpg");

//HERE I ROUND DEGRE PARAMETER BECAUSE imagefilledarc only accept integers
(I prefer it rounded than truncated)
$lNumDegre=round($lDegre);
$lResult|=imagefilledarc ($image , 460 , 474 , 2*430 , 2*430  , -$lNumDegre
, 0, $colorGreen , IMG_ARC_PIE );
$lResult|=imagecopymerge($image, $fond, 0, 0, 0 , 0, $lSizeX,$lSizeY,75);
imagejpeg($image, "temp.jpg");
imagedestroy($image);
echo file_get_contents("temp.jpg");

Expected result:
----------------
imagefilledarc should accept float parameters for "start" and "end"
parameters.
As you can see on sample at
http://mon-convertisseur.fr/php/imgangle.php?DEGRE=172.3
green backgound
allways fall on a degre graduation  of the protactor.
