Question: is an option velocity in DEplot implemented?

Two options for DEplot, "velocity" and "color=velocity" are referred to in the Maplesoft conference presentation below, but don't work on my Maple13. Were these options ever implemented? Do they require a call to a special package (no mention of that in the presentation below, dated 2005)? These are very nice options, so if you know anything about them or something similar, I'd appreciate very much your suggestions.
