-# First: xcf2png by default calls zcat rather than gzcat. This is
-# totally always broken; zcat forces a .Z extension on its input
-# filename. So we can't rely on xcf2png's default behavior. But it
-# offers -Z for a custom decompression program.
-#
-# BUT: Gimp produces gz files with some padding zeros because, I don't
-# know, someone might want to save their compressed xcfs to DECtape.
-# gzip has a -q option to not *print* the warning associated with this
-# harmless thing, but then goes ahead and exits non-zero anyway, which
-# makes xcf2png barf and die before writing anything even though it
-# got perfectly good data.
-#
-# So: 1) use gunzip, 2) manually feed it to xcf2png, 3) hope nothing is
-# set to die based on pipe status, 4) hope that if the xcf data is
-# actually busted xcf2png will do something helpful.
