Bug description: imagefilledpolygon doesn't antialias
Description:
------------
When creating images, if antialias is enabled with imageantialias() lines
and polygons are drawn with antialiasing, but filled polygons are not.
PHP version used is latest stable CVS with bundled GD library.
Reproduce code:
---------------
<?php
$image = imagecreatetruecolor(400, 250);
imageantialias($image, TRUE);
$bg = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $bg);
$points[] = 50;
$points[] = 75;
$points[] = 100;
$points[] = 200;
$points[] = 350;
$points[] = 50;
$color = imagecolorallocate($image, 200, 0, 0);
imagefilledpolygon($image, $points, 3, $color);
header('Content-type: image/png');
imagepng($image);
?>
Expected result:
----------------
The outside lines of the polygon in the image created by the above code
should be antialiased.
Actual result:
--------------
The outside lines of the polygon appear the same as they do when
antialiasing is turned off. If you substitute imagepolygon for
imagefilledpolygon, you will see that the unfilled polygon is indeed drawn
antialiased; this is what I had expected to see.
