New Comment:
The bug can be found in every PHP-Version, but I don't have enough time
to test a snapshot or run the script on our linux servers.
Once I found a patch for that problem, but it is very troublesome to
change the code everytime you compile php. Maybe it can be helpfull for
you.

Yes, in what version? Please, update the version field whenever you try
some snapshot / release / etc. so we don't have to ask for it all the
time..

Description:
------------
the imagearc and imagefilledarc functions don't seem to support images
using truecolor and alphablending.
In the following example I don't need alphablending, but I require it
to use other images as background.
Reproduce code:
---------------
<?php
//outputs strange image
$img = imagecreatetruecolor(100, 100);
//works fine using palette image instead
//$img = imagecreate(100, 100);
imagesavealpha($img, true);
imagealphablending($img, true);
$transparent = imagecolorallocatealpha($img, 255, 255, 255, 80);
//make the background transparent
imagefill($img, 0, 0, $transparent);
$color = imagecolorallocatealpha($img, 0, 255, 0, 100);
imagefilledarc($img, 49, 49, 100, 100, 0 , 359, $color, IMG_ARC_PIE);
header('content-type: image/png');
imagepng($img);
?>
Expected result:
----------------
Same result as using the paletteimage version.
Actual result:
--------------
Strange looking arcs and filled arcs.
