Remove damned ancient DOS line endings from Irrlicht. Hopefully I did not go overboard.

- * cjpeg.c

- *

- * Copyright (C) 1991-1998, Thomas G. Lane.

- * Modified 2003-2011 by Guido Vollbeding.

- * This file is part of the Independent JPEG Group's software.

- * For conditions of distribution and use, see the accompanying README file.

- *

- * This file contains a command-line user interface for the JPEG compressor.

- * It should work on any system with Unix- or MS-DOS-style command lines.

- *

- * Two different command line styles are permitted, depending on the

- * compile-time switch TWO_FILE_COMMANDLINE:

- *      cjpeg [options]  inputfile outputfile

- *      cjpeg [options]  [inputfile]

- * In the second style, output is always to standard output, which you'd

- * normally redirect to a file or pipe to some other program.  Input is

- * either from a named file or from standard input (typically redirected).

- * The second style is convenient on Unix but is unhelpful on systems that

- * don't support pipes.  Also, you MUST use the first style if your system

- * doesn't do binary I/O to stdin/stdout.

- * To simplify script writing, the "-outfile" switch is provided.  The syntax

- *      cjpeg [options]  -outfile outputfile  inputfile

- * works regardless of which command line style is used.

- * This routine determines what format the input file is,

- * and selects the appropriate input-reading module.

- *

- * To determine which family of input formats the file belongs to,

- * we may look only at the first byte of the file, since C does not

- * guarantee that more than one character can be pushed back with ungetc.

- * Looking at additional bytes would require one of these approaches:

- *     1) assume we can fseek() the input file (fails for piped input);

- *     2) assume we can push back more than one character (works in

- *        some C implementations, but unportable);

- *     3) provide our own buffering (breaks input readers that want to use

- *        stdio directly, such as the RLE library);

- * or  4) don't put back the data, and modify the input_init methods to assume

- *        they start reading after the start of file (also breaks RLE library).

- * #1 is attractive for MS-DOS but is untenable on Unix.

- *

- * The most portable solution for file types that can't be identified by their

- * first byte is to make the user tell us what they are.  This is also the

- * only approach for "raw" file types that contain only arbitrary values.

- * We presently apply this method for Targa files.  Most of the time Targa

- * files start with 0x00, so we recognize that case.  Potentially, however,

- * a Targa file could start with any byte value (byte 0 is the length of the

- * seldom-used ID field), so we provide a switch to force Targa input mode.

+ *      cjpeg [options]  inputfile outputfile
+ *      cjpeg [options]  [inputfile]
+ * In the second style, output is always to standard output, which you'd
+ * normally redirect to a file or pipe to some other program.  Input is
+ * either from a named file or from standard input (typically redirected).
+ * The second style is convenient on Unix but is unhelpful on systems that
+ * don't support pipes.  Also, you MUST use the first style if your system
+ * doesn't do binary I/O to stdin/stdout.
+ * To simplify script writing, the "-outfile" switch is provided.  The syntax

+ * To determine which family of input formats the file belongs to,

+ * guarantee that more than one character can be pushed back with ungetc.
+ * Looking at additional bytes would require one of these approaches:
+ *     1) assume we can fseek() the input file (fails for piped input);
+ *     2) assume we can push back more than one character (works in

+ * or  4) don't put back the data, and modify the input_init methods to assume
+ *        they start reading after the start of file (also breaks RLE library).
+ * #1 is attractive for MS-DOS but is untenable on Unix.
+ *
+ * The most portable solution for file types that can't be identified by their
+ * first byte is to make the user tell us what they are.  This is also the
+ * only approach for "raw" file types that contain only arbitrary values.
+ * We presently apply this method for Targa files.  Most of the time Targa
+ * files start with 0x00, so we recognize that case.  Potentially, however,
+ * a Targa file could start with any byte value (byte 0 is the length of the
+ * seldom-used ID field), so we provide a switch to force Targa input mode.
