[FIX](PointPlot ignoreNulls nullInterpolationMode) When not ignoring nulls and the null interpolation mode was not none, the point (area, line, dot) plot was not recognizing interpolated scenes. Some interpolation scenes have both the null datum and the interpolated one, which confused the rpevious detection method.
[FIX](AxisPanel LabelSpacing Vertical Number Ticks) The min label spacing for numeric label ticks, in vertical cartesian axes, was sometimes not being respected. Also fixed some AxisPanel existing bugs that surfaced when this one was uncovered.
