/*! The DTS file format stores in separate buffers values of 8, 16 or 32
bits of length, in order to speed up loading in non-Intel platforms.
In order to create a DTS file you should create the three buffers in
memory and then begin writting the data using helper functions. This
mimics the way the data is retrieved in the engine.
This class provides the needed functionality. Simply create a
OutputStream object and write the data using the "write" method,
that stores the values in the correct buffer. The "flush" method
creates finally the file in the format expected by the V12 engine.
The class knowns about all DTS namespace simple objects and can
save them (operator <<) in the expected format.
*** WARNING *** THIS CODE IS NOT PORTABLE
This code assumes a little-endian 32 bits machine
