Enclosed is a patch file for the wavlelet/dwt.c file that speeds up the
operation of the dwt_step function a bit by eliminating the need for the
program to calculate the buffer offset repeatedly. The dwt.c file contains
the updated code.



It increases speed at the cost of slightly more complicated code.
