* Updating directed path leg with offsets fails to update correctly
   * Implementation mixed current location and desired location, and was
unnecessarily calculating same information repeatedly.
* Moving a path leg end (elbow) so that other end (elbow) overlaps a
nozzle causes misalignment of inline component (pipe) between the leg
ends.
   * Recursive update overwrote correctly calculated position and
orientation with out dated data.

Mesh hover highlights were corrupted when objects were zoomed close.
This is a workaround that creates a separate Actor for edges.

VTK 9.2 compatibility patch for simantics.G3D.

Changed Plant3DEditor dispose logic to prevent VTK / Active GL Context
errors.

gitlab #173

Updated VTK library to 9.2.2

Note: There are several changes to the original code in vtk.rendering
plug-in.
* Originally, VTK was outputting black window. There seemed to be a
conflict with double buffering, and disabling it fixed the issue.
* VTK SWT binding was not designed to be deleted runtime (or at least it
did not work).

gitlab #173

As a bonus, made some improvements to debugging methods.

Reversing direction requires recalculation of rotation angle. In
degrees: newAngle = 360 - oldAngle.

Too loose angle check caused zero length elbows, which the led to path
legs with no direction.

Turn component's parameters were omitting turnAngle on loadup. Thus the
geometry updates never reacted to turnAngle changes.

gitlab #163

Calculating a new position for a turn that approaches infinity is not a
good idea.

gitlab #163

Calculating orientation of control point did not work.

gitlab #163

spaceForTurn turn can be called when path leg end is not directed /
nozzle.
There is a bug, which causes disposed control points to be updated.
Created a workaround.

And as a bonus, adjusted VTK clip planes to prevent near clipping plane
hiding objects.
