The fix for PHP bug 43828[1] changed the algorithm from drawing filled pies from drawing multiple triangles to drawing a single polygon. Due to quirks of the filled polygon drawing algorithm, we had to filter out extraneous vertices. This lead, however, to a bug regarding displaced starting and ending points near 90° and 270° degrees, which we fix by reinserting these vertices if they had been removed. This fix is a port of libgd/libgd@1406b1a. [1] <https://bugs.php.net/bug.php?id=43828>
