[GRASS-dev] backwards sliders in NVIZ

[Michael Barton]

I'm doing a bunch of bug fixes in gism. But I can take a look at this
afterwards.

Do you need to change the resolution setting? This sets the increment
interval.

Command-Line Name: -resolution
Database Name: resolution
Database Class: Resolution
    A real value specifying the resolution for the scale. If this value is
greater than zero then the scale's value will always be rounded to an even
multiple of this value, as will tick marks and the endpoints of the scale.
If the value is less than zero then no rounding occurs. Defaults to 1 (i.e.,
the value will be integral).
