Give the user the option of cancelling a file open if there are
segment zones; otherwise they're converted to polygon fills.

Allows 0 to 4 chamfered corners, not only one.
A custom shape allow this kind of shape. However because it is a primitive,
it is easier to edit and it support thermal reliefs.
gal: pixel alignment for Cairo.
gal: pixel alignment for OpenGL
Cleanup of pixel alignment patches
gal/opengl: more pixel alignment patches:
- works on Retina displays now
- pixel alignment for circles
- correct 1-pixel strokes
- fixed unfinished 1-pixel line ends
GAL: Restore antialiasing options in Cairo
GAL: Fix arc drawing
Removes DrawArcSegment, which drew arcs whose edge was optionally
stroked (a feature that we did not use). Fixes Cairo arc drawing issue
where arcs were not visible in pcbnew.
gal: further cleanup
gal: removed unused shader parameter
the stroke mode was always activated, even in fill mode. creating incorrect size shape for null length track segments.

The standard DIM() macro was not typesafe as it happily deferred errors
to runtime that can be caught at compile time. Replacing it with a
generic C++11 constexpr allows for typecasting, comparison and compile
time error checking.
Use TesselatePolygon() to draw polygons in Gerbview instead of GLU tesselation, much slower.
Add helper methods in GAL to know if the current GAL engine is Cairo, OpenGL or something else,
useful to optimize drawing code.
IsPolygonFilled() replaces the hard coded comparisob with Edge_Cut in code.
For now the polygon is not filled only on Edge_Cut layer.
But in the future, it could be an option for other layers.
Like circles, polygons are self-closed elements that define an outline.
This allows them to be used as such for board outlines and cutouts.

In DRAWSEGMENT polygonal shape: the commit tried to use triangulation (CacheTriangulation) to draw the shape (similar to zones).
It was much faster than using GLU tesselator (one order of magnitude).
Unfortunately, CacheTriangulation() works only with simple polygons, not with any polygon.
And simplifying a polygon with a lot of vertexes is very time consuming.
So using CacheTriangulation() is now removed and GLU tesselator is used as previously.

SEGZONE types were confusingly named PCB_ZONE_T. Zones in pcbnew are
now _only_ PCB_ZONE_AREA_T, so we name segzone types PCB_SEGZONE_T to be
clear.
This also removes processing of the SEGZONEs from connectivity
calculations.
Rename GetPolyPoint() to BuildPolyPointsList(), because GetPolyPoint() looks like an accessor, but it is not an accessor.
(Using it as accessor can creates a *very long calculation time* for very basic access to polygon vertices)

Zones: it turned out that for every zone point, the set of hatch lines
has been drawn, resulting in numerous redundant lines. Now the set is
drawn only once per zone.
Custom shape pads: as GAL supports SHAPE_POLY_SETs, there is no need to
create a temporary vector to copy there a list of points to be drawn.
Changed the drawing calls to use SHAPE_POLY_SETs directly.
Thanks to Andreas Buhr patch, code for drawing filled polygons and their
outlines has been unified. Previously it was done by changing the
drawing method (GAL::DrawPolygon() vs GAL::DrawPolyline()), now it is
done by modifying attributes (stroke/fill).
LAYER_NON_PLATED to LAYER_NON_PLATEDHOLES
LAYER_PADS_HOLES to LAYER_PADS_PLATEDHOLES
LAYER_PADS to LAYER_PADS_TH
and add comments and fix a render issue in gal mode for non plated holes.
