Fix #53580: During resize gdImageCopyResampled cause colors change
We port the upstream fix[1], and also revert commit a3383ac3d7[2] which
is now obsolete, and also not part of libgd. Especially the change to
gd.png.c was at best a half-baked optimization.

Fix #73614: gdImageFilledArc() doesn't properly draw pies
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.
