-    Abstract:
-
-        This file contains the implementation of CNV12Synthesizer.
-        
-        CNV12Synthesizer is derived from CYUVSynthesizer.  It uses the YUV color
-        space and defines a Commit() function that reformats pixels into the 
-        NV12 format.  From MSDN:
-
-            A format in which all Y samples are found first in memory as an 
-            array of unsigned char with an even number of lines (possibly with 
-            a larger stride for memory alignment). This is followed immediately 
-            by an array of unsigned char containing interleaved Cb and Cr 
-            samples. If these samples are addressed as a little-endian WORD 
-            type, Cb would be in the least significant bits and Cr would be in 
-            the most significant bits with the same total stride as the Y 
-            samples. NV12 is the preferred 4:2:0 pixel format.
-

-Routine Description:
-
-    Copy (and reformat, if necessary) pixels from the internal scratch
-    buffer.  If the output format decimates chrominance, do it here.
-
-Arguments:
-
-    Buffer -
-        The output buffer to fill.
-
-    Size -
-        The size of the output buffer in bytes.
-
-    Stride -
-        The length of a row in bytes.
-
-Return Value:
-
-    Number of bytes copied into Buffer.
