* Allow Color and Effects on Data Points on Chart Axis
Fix#3414. There had been no way to do this. It is now supported via a new AxisText class, which derives from Properties, and has FillColor and effects (glow/shadow/softEdges) properties. The code changes in chart sample 33_Chart_create_scatter2 illustrate usage.
* Minor Performance Improvement
May also get rid of Scrutinizer complaint.
* Eliminate New Spacing Patch
No need for it.
* Add Legend Formatting to Change
Much in common with Data Point formatting.
