      Fix segfault when opening input/queue/id:000007,src:000000,op:flip1,pos:51 with feh
      Make IMAGE_DIMENSIONS_OK() more restrictive
      load_pnm: Deal with fread() errors consistently
      __imlib_LoadImage(): Additionally check loader_ret to detect loader failures
      loader_tga: Abort file loading if the file obviously isn't large enough
      imlib_save_image(): Check loader return code for errors
      loader_tga.c: Properly signal if decoding uncompressed BGRA data failed
      loader_tga.c: Properly signal if decoding RLE compressed data failed
      imlib_save_image_with_error_return(): Check loader return code to prevent use of unitialized memor
