+;Get a value
+;compare it with the value before it
+;find closest value in table and store the index into the table
+;if i'm going down then negitize it
+;go to next byte.
+
+;Theory for stereo:
+;1)handle stereo and mono in two seperate loops. cleaner...
+;start at byte 0 and skip every other byte(or word) both write and read
+;when we get done
+;	set start byte to 1 and do it again
+
+
+
+
+;This table essentialy round off to closes values in 3 distinct bands
+; precalculated and optimized(i guess) for human hearing.

+;*     sosCODECDecompressData - Decompress audio data.
+;*
+;* SYNOPSIS
+;*     Size = sosCODECDecompressData(CompInfo, NumBytes)
+;*
+;*     long sosCODECDecompressData(_SOS_COMPRESS_INFO *, long);
+;*
+;* FUNCTION
+;*     Decompress data from a 4:1 ADPCM compressed stream. The number of
+;*     bytes decompressed is returned.
+;*
+;* INPUTS
+;*     CompInfo - Compress information structure.
+;*     NumBytes - Number of bytes to compress.
+;*
+;* RESULT
+;*     Size - Size of decompressed data.

+;*
+;*     long sosCODECDecompressData(_SOS_COMPRESS_INFO *, long);
+;*
+;* FUNCTION
+;*     Decompress data from a 4:1 ADPCM compressed stream. The number of
+;*     bytes decompressed is returned.
+;*
+;* INPUTS
+;*     CompInfo - Compress information structure.

+;*
+;* RESULT
+;*     Size - Size of decompressed data.
+;*
+;*
+;* NOTES
+;*     This routine has been optimized for pipelining on both
+;*     486 and Pentium processors.  Changing, inserting, or moving any
+;*     instructions will most likely slow down the code, in some cases by
+;*     as much as 20%.  It can burst-decompress 16384 samples in about
+;*     1940<34>s on a Pentium 90Mhz, and about 3960<36>s on a 486 66Mhz.
+;*     Instruction reordering could bring this down to below 1870<37>s on
+;*     the Pentium, but this would cause a great degradation in 486
+;*     performance.  Since slow 486's are the reason this code was
+;*     written to be fast, it has been optimized for the Pentium only where
+;*     it would not degrade 486 performance.  So, be careful when changing
+;*     ANY of this code, because it is very carefully balanced...

+;*
+;* SYNOPSIS
+;*     Size = sosCODECDecompressData(CompInfo, NumBytes)
+;*
+;*     long sosCODECDecompressData(_SOS_COMPRESS_INFO *, long);
+;*
+;* FUNCTION
+;*     Decompress data from a 4:1 ADPCM compressed stream. The number of
+;*     bytes decompressed is returned.
+;*
+;* INPUTS
+;*     CompInfo - Compress information structure.
+;*     NumBytes - Number of bytes to decompress.
+;*
+;* RESULT
+;*     Size - Size of decompressed data.
+;*
+;*
+;* NOTES
+;*     This routine has been optimized for pipelining on both
+;*     486 and Pentium processors.  Changing, inserting, or moving any
+;*     instructions will most likely slow down the code, in some cases by
+;*     as much as 20%.  It can burst-decompress 16384 samples in about
+;*     1940<34>s on a Pentium 90Mhz, and about 3960<36>s on a 486 66Mhz.
+;*     Instruction reordering could bring this down to below 1870<37>s on
+;*     the Pentium, but this would cause a great degradation in 486
+;*     performance.  Since slow 486's are the reason this code was
+;*     written to be fast, it has been optimized for the Pentium only where
+;*     it would not degrade 486 performance.  So, be careful when changing
+;*     ANY of this code, because it is very carefully balanced...

+; the rectangle to find out if the rectangle is:
+; - trivially accepted (no further clipping test, display rectangle)
+; - trivially rejected (return with no action)
+; - retangle must be iteratively clipped again edges of the clipping window
+;   and the remaining retangle is display.
