The plug-in tells the data size to network builder which allocates
the buffers for a particular instantiation of that plug-in.
Engine actually doesn't have to know the data size but it depends
on the implementation.
And, "samples to process" is not necessarily related to any buffer sizes.

If you want fix the data type to float, it is known that the data size
is 4. Otherwise, plug-in has to have routines for getting the data size.
Very simple additions are needed to support different stream types.
Let the engine author decide how it delivers this info from the plug-in
to the engine. Don't fix the engine too.
