{ This file contains simple error-reporting and trace-message routines.
These are suitable for Unix-like systems and others where writing to
stderr is the right thing to do. Many applications will want to replace
some or all of these routines.
These routines are used by both the compression and decompression code. }

{ Error exit handler: must not return to caller.
Applications may override this if they want to get control back after
an error. Typically one would longjmp somewhere instead of exiting.
The setjmp buffer can be made a private field within an expanded error
handler object. Note that the info needed to generate an error message
is stored in the error object, so you can generate the message now or
later, at your convenience.
You should make sure that the JPEG object is cleaned up (with jpeg_abort
or jpeg_destroy) at some point. }
