Graph Builder: Points with identical x/y position

[#1]

Graph Builder applies a clever scheme to determines which data points are actually processed.


Findings:

• objects (raw x/y values)  outside the plot window are not displayed (e.g. x=1)
• objects with IDENTICAL x and y values are displayed as a single object (the first one)
• selected objects are displayed (even if it's a "second" object)
  analogously: objects with a marker/color row state are displayed
• objects with different x values are displayed as multiple objects (tiny offsets like 1E-10 are enough)
• objects with different Y values are displayed as multiple objects (an offset of 0.01 is enough, 0.001 is not enough)
• objects with same x/y values, but different COLOR are displayed as multiple objects (sure: same holds for Overlay)
  
  
• The effects are nicely visible for Marker Draw Expr(), but the same should hold for standard Markers as well.
  [For standard Markers, the functionality is difficult to detect, for Marker Draw Expr()it can have significant effects.]
