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.
SHAPE_POLY_SET: fix crash in VertexCount when it is a empty poly set, or when params are incorrect.
minor other fixes:
warning in degug mode in dialog_dxf_import_base.cpp
pcb_painter.cpp: remove a useless debug line.
- pad names are stored as wxString instead of a char[4] & integer union
- removed pad name to string conversion functions
- fixed pad & pin properties dialog restrictions regarding the name
length
- support for background color setting
- removed several global config settings (such as g_Drc_On)
- wrapped most of global config settings in PCB_GENERAL_SETTINGS class
- reorganized PCB general options dialog to clearly mark which options concern only the legacy canvas
- new GAL feature for legacy users: double-click (or E) to change track width available as an option.
