ITK needs to work both with a CVS version of VXL and a periodically
updated copy.  As the API changes (like resize->set_size) I need to be
able to have ITK detect which API is present.  I can do this by looking in
CVS logs for the day on which the change was made and then use #if checks
based on VXL_VERSION_DATE_FULL to exactly match the change down to the
day.

This gives us a very low-maintenance, high-resolution way of having API
version numbering with no human interaction.  Fred Wheeler also pointed
out that it would be a way to confirm that the cvs mirrors are updating
correctly.
