Subject: - Patch #373613 by quicksketch and drewish: in order to operate on
 images multiple   times (such as crop, scale, then desaturate) without
 quality loss, we need to   pass images by their raw GD (or other library)
 resources rather than re-opening   the same image repeatedly, which causes
 wasted processing and loss of quality when   using JPEG images.  This patch
 reworks the image toolkits, adds some new image   manipulations and adds some
 impressive SimpleTests.
