Restore point cloud for text data, get rid of the ClassCastException
when clipping the data.
Take the time to improve the ZIDV data saving dialog.  If you are going
to have 2 mutually exclusive options - use radio buttons and set a
default. Inset the data source checkboxes and fix the problem with local
file names being on a different line than the checkbox.  Making things
work is part of the solution.  Making the user experience better is
worth the extra effort.
