-wxCountingOutputStream is specialized output stream which does not write any data anyway,
-instead it counts how many bytes would get written if this were a normal stream. This
-can sometimes be useful or required if some data gets serialized to a stream or compressed
-by using stream compression and thus the final size of the stream cannot be known other
-than pretending to write the stream. One case where the resulting size would have to be
-known is if the data has to be written to a piece of memory and the memory has to be
-allocated before writing to it (which is probably always the case when writing to a 
-memory stream).
