- with the xml append format it is possible to write raw binary
(instead of base64), but the writer becomes more complicated.
Either needs two passes to create, or need to allocate a block
of space for the header information (like VTK itself does) and
write later.
* internalWriter
* patchWriter
* surfaceMeshWriter
* lagrangianWriter
Also these special purpose ones:
