=============================================
Angle constraints are internally coded using the diverging points of the segments (PointPos != none) in normal 2 segment angle constraints.
This creates a problem with the mechanism to transfer enpoints on angle deletion.

========================================
Now the Grid is calculated based on the maximum semiaxis length. Grid is recalculated on every redraw of the Sketcher.
========================================
Axes size was bounded to the boundingbox of the underlaying 2D shape. However, this does not even get updated in no update mode and provides unreliable values.
The axes calculation now:
- is coded to be the same size and fully symmetric.
- is coded to be minimum 100 mm semiaxis, which gives a good impresion for empty sketches with default zoom.
- is coded to grow with the largest of the semiaxes.

=========================================================
Before this commit equality line to circle is allowed although the solver can not process it.
Similar happens for several combinations of incompatible edges.
===============================================
It is a long felt need that redundant constraints are not generated while autoconstraining.
The solver sketcher in v0.17 is überpicky with redundants due to the new popularity contest algorithm. The former behaviour is exhacerbated.
This new mode enables automatic redundant constraint removal.
In UI operations IN EDIT MODE, upon detection of redundancy by the solver, the Sketcher will remove all redundant constraints detected by that solve.
This makes the sketcher much less annoying.
How to test this?
The easiest example is to create a vertical line. Then make the endpoints symmetric with respect to the horizontal axis. Without this mode,
the vertical constraint and the symmetry constraint are redundant. With this mode, the vertical constraint gets automatically removed by the Sketcher.
==============
- Zero initialization of the jacobian matrix
- Correct notification of redundant/conflicting in presence of non-driving constraints.

+ add signal showFormulaDialog to QuantitySpinBox in order to indicate whether the formula dialog opens or closes
+ when formula dialog opens then hide the button box in the parent dialog, show it again when the formula dialog closes
