-Subject: [PATCH] Fix #420: Potential infinite loop in gdImageCreateFromGifCtx
-
-Due to a signedness confusion in `GetCode_` a corrupt GIF file can
-trigger an infinite loop. Furthermore we make sure that a GIF without
-any palette entries is treated as invalid *after* open palette entries
-have been removed.
