Message:

handle errors in dvo I/O functions; better support for DIS images; merge in high-speed mods from Niall; systematic errors in astrometry (somewhat hackish); add fits I/O option to succeed reading a short file (padding as needed); various kapa improvements (frames consistent in X, PS, PNG; fix tick label signif digits; add function for image overlays; better thick box lines; PNG of the image); bDrawBuffer mods to drop static buffer and refer to passed through buffer; ResizeByImage; DefineSectionByImage; buutos to do png & jpeg; add program roc for raid over cluster; support for mosaic photcodes in dvo image plot; densify; section name [-image x y] : width based on current image; resize -by-image; threaded addstar -resort; threaded dvomerge; dvorepair; dvoverify; dvomerge continue; dvomerge from list (of regions)
