Matthias Koefferlein 94387529d6 Fixed #134 
The issue was caused by an internal error in the edge processor.
Effectively the weak attractor scheme was causing this problem.
As the weak attractors are making things worse rather than
better I dropped them.

In theory, the weak attractors render an edge undisturbed by
neighboring intersection points, but in cases or parallel edges
this lead to problems: omitting cut points violates the output
edge configuration warranties the the polygon stitcher fails.

In addition, to maintain the solution for bug #74, the cut point
capture condition was relaxed, so that edge crossing the exact
corner of the snapping rectangle of a point are not considered
captured.

Matthias Koefferlein 067d52a269 FEATURE: DXF accuracy and "keep layer names" feature 
* "keep layer name" will not try to modify layer names into
  GDS layer/datatypes. The feature is available in the DXF
  reader options and for the buddy scripts as "--keep-layer-names"
  It applies to CIF too.
* "contour accuracy": when merging lines into contours, this
  accuracy is applied to find neighbors. By default this value
  is 0. If set to a value >0, points with distances (square
  metrics) less than this value will be connected.
  The buddy script option is --dxf-contour-accuracy=value.

Matthias Koefferlein 6052a04429 A few enhancements and unit tests for PCells 
This commit adds unit tests for implementation helper-based
PCells in Python and Ruby.

Matthias Koefferlein f6f75cd791 A small rework of the Python PCell helpers 
The aim of this rework was to enable PCell implementations
that use the basic methods rather than the "_impl" variants.
For the latter, potential variable name clashes happen when
parameters are called "cell", "layout", "layer" or similar.

New methods enable implementation on the level of the
non-"impl" methods. For example:

  def produce(self, layout, layers, parameters, cell):
    self.init_values(parameters, layers)
    ...
    self.finish()

Matthias Koefferlein 6d0fe85425 Fixed #75 (Python PCell issue when parameters are called 'layer') 
This commit
- Ignores exceptions when checking for PCells that accept shapes.
  Hence a single rogue one does not break the feature.
- Prevents errors when parameters named "layer" are present
  by making the implementation safe against this case.
- In addition, guiding shape parameters of type "Path", "Box" etc.
  (i.e. integer types) are supported too although they are
  not recommended for portability.

klayoutmatthias 7e0f1522ac Windows build compatibility 
The issue is with "dllexport": previously, dllexport was present on
exposed templates tool (= visibility(default) for gcc/clang). This
ensured MacOS compatibility since then the typeinfo is corretly
shared and dynamic_cast/typeid works.

For Windows, the "dllexport" equivalent requires the template
instantiations to be declared "external" which is a coding nightmare.

The solution is to provide separate macros for real (non-specialized,
not explicitly instantiated) templates (.._PUBLIC_TEMPLATE) which
is defined as empty for Windows and "visiblity(default)" for gcc/clang.

matthias 063811edc4 Solved the clang/MacOS startup failure and menu issue 
1.) Startup issue:

This is solved by making sure templates with virtual functions
are made visible in the DSO. This way, dynamic_cast is possible
across DSO's.

Scary: clang/MacOS wants the forward declarations be declared visible as well.

2.) Menu issue:

The best solution is to have only one QMenuBar. The navigator
now gets a synthetic menu bar composed of QToolButtons.
