//! Restriction: needs to allocate a buffer large enough to hold a complete 
//! image file. But we don't know its size before it's actually encoded, so 
//! we have to be generous or "accidents will happen" 
//! A better implementation would rely on memory-mapped files or implement 
//! dynamic buffering.
