To clarify:
* To include the option to transparently compress/read data does not mean
*require* the use of compressed data.
* The issue of including widely useful mechanisms for data
compression as part of the core capabilities of vtk is separate
from making it easier to add extensions to vtk. Both should be done,
I think. Reading compressed streams is a core capability, not restricted
to a single vtk module.
* vtk data files of sparse data can easily zip down by a factor of ten or one
hundredfold. Knowing that compression is available for those kinds
of files as a core property of vtk changes how you think about dealing
with those files completely, and for the better.
* the use of a standard compression method means that external tools can
still be used to manipulate the vtk data. You're not locking anyone in
to anything.

Ps. The TIFF distribution doesn't ship with LZW anymore because of patent
problems. zip doesn't have those problems.
