[Kst] [Bug 128483] UI: the "quick curve creation" part of the equation dialog should be clearly separated

Nicolas is correct that this is confusing, but the solution is, unfortunately, 
wrong.  Do not commit this patch.

The problem is that the 'x' vector serves two purposes:

  1) the X vector in the auto-created curve
  2) the vector that replaces 'x' in equations (eg, when you enter x^2)

In the ancient "barth programs kst on the subway for fun and no one else has 
even heard of it" days, equations were a type of curve, and the concepts were 

Then equations ceased to be curves and became data objects, and the natural 
association went away.  So in some sense, there should be an entry for the 
curve's X, and an entry for the equation's x.  But if you are creating a new 
equation you will certainly want X and x to be the same....  But now, once 
you have created the curve and the equation, this association ceases, as you 
might plot the eq-sv verse something else with the curve dialog.

So the "edit equation" version of the dialog doesn't have anything about the 
curve.  But you do want/need to be able to edit what you mean by 
'x' (definition 2).

In any case, the "Interpolate to highest resolution vector" has nothing to do 
with curve creation.  It refers to how the equation should deal with 
different length vectors used by the equation.  It also must be in the edit 
equation version of the dialog.

We need a solution to this problem though.
