/* How do the loaders behave when memory is low?
It depends on the state the above tests left the
memory in.
- Sometimes the png loader tries to report an
"out of memory", but then g_strdup_printf() calls
g_malloc(), which fails.
- There are unchecked realloc()s inside libtiff, which means it
will never work with low memory, unless something drastic is
done, like allocating a lot of memory upfront and release it
before entering libtiff. Also, some TIFFReadRGBAImage calls
returns successfully, even though they have called the error
handler with an 'out of memory' message.

It depends on the state the above tests left the
memory in.
- Sometimes the png loader tries to report an
"out of memory", but then g_strdup_printf() calls
g_malloc(), which fails.
- There are unchecked realloc()s inside libtiff, which means it
will never work with low memory, unless something drastic is
done, like allocating a lot of memory upfront and release it
before entering libtiff. Also, some TIFFReadRGBAImage calls
returns successfully, even though they have called the error
handler with an 'out of memory' message.
