* NOTE:
* This is a modified version of the openjpeg dwt.c file.
* Average speed improvement compared to the original file (measured on
* my own machine, a P4 running at 3.0 GHz):
* 5x3 wavelets about 2 times faster
* 9x7 wavelets about 3 times faster
* for both, encoding and decoding.
*
* The better performance is caused by doing the 1-dimensional DWT
* within a temporary buffer where the data can be accessed sequential
* for both directions, horizontal and vertical. The 2d vertical DWT was
* the major bottleneck in the former version.
*
* I have also removed the "Add Patrick" part because it is not longer
* needed.
