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

- * jfdctflt.c

- *

- * Copyright (C) 1994-1996, Thomas G. Lane.

- * Modified 2003-2009 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 floating-point implementation of the

- * forward DCT (Discrete Cosine Transform).

- *

- * This implementation should be more accurate than either of the integer

- * DCT implementations.  However, it may not give the same results on all

- * machines because of differences in roundoff behavior.  Speed will depend

- * on the hardware's floating point capacity.

- *

- * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT

- * on each column.  Direct algorithms are also available, but they are

- * much more complex and seem not to be any faster when reduced to code.

- *

- * This implementation is based on Arai, Agui, and Nakajima's algorithm for

- * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in

- * Japanese, but the algorithm is described in the Pennebaker & Mitchell

- * JPEG textbook (see REFERENCES section in file README).  The following code

- * is based directly on figure 4-8 in P&M.

- * While an 8-point DCT cannot be done in less than 11 multiplies, it is

- * possible to arrange the computation so that many of the multiplies are

- * simple scalings of the final outputs.  These multiplies can then be

- * folded into the multiplications or divisions by the JPEG quantization

- * table entries.  The AA&N method leaves only 5 multiplies and 29 adds

- * to be done in the DCT itself.

- * The primary disadvantage of this method is that with a fixed-point

- * implementation, accuracy is lost due to imprecise representation of the

- * scaled quantization values.  However, that problem does not arise if

- * we use floating point arithmetic.
