Bug description: imagecopymergegray produces mosaic rainbow effect
Description:
------------
When merging two images, one normal and the other one completely black,
the output from imagecopymergegray produces a weird looking mosaic of the
first.
Reproduce code:
---------------
<?php
$imPng = imagecreatefrompng("Tiles/Bamboo/9.png");
$imSrc = imagecreatefrompng("Tiles/Bamboo/black.png");
$height = imagesy($imPng);
imagecopymergegray($imPng, $imSrc, 0, 0, 0, 0, $height, $height, 50);
header("Content-type: image/png");
imagePng($imPng);
?>

earlier version (4.3.10).
Actual result:
