For some image types, it is a simple matter of passing to the library
the limits Emacs wants to set. For libpng, we could use
png_set_user_limits() to set our maximum width/height. (libpng also has
a built-in default limit of 1 million pixels in both dimensions.)
For other libraries, the application can set the maximum amount of
memory to allocate, see for example libjpeg's `max_memory_to_use' and
`max_alloc_chunk'.
Getting things right for all image types will probably be tricky...
