Jeff Young 393bb0fd83 Fix assert where geometry routine wasn't ready to handle layers.
This introduces layer handling to a lot of the geometry routines.
Many of them don't do much with it now, but it does help multi-layer
zones and will help when padstacks are implemented.

Jeff Young 463100d67f Remove a long-standing hack to keep divots out of adjacent zones.
The new algorithm unions any adjacent zones before doing the
chamfer/fillet and then subtracts the other zones back out afterwards.

jean-pierre charras eae739d98e ZONE_CONTAINER::TransformSolidAreasShapesToPolygonSet(): for polygons with outline

jean-pierre charras 9c817638d9 ZONE_CONTAINER::TransformSolidAreasShapesToPolygonSet(): fix incorrect transform
For zones filled using the new algo (filled areas without thickness), a outline

Jeff Young d01b29ab37 Cleanup pad geometry handling.
There were a lot of plotters, exporters, etc. that were rolling their
own implementations.

This also introduces a lazily-built set of SHAPE objects for doing
collision detection and some forms of rendering (and later DRC).

Jeff Young e1d5cf1a87 Change pad solder masks to use rounded-corner clearances.
This assumes maximum registration errors are a vector, rather than
an amount in both x and y axes.  Lots more disucssion in the bug
report and on the forum (link in the bug report).

Also makes large changes to the painting of pads, but they now use
the same code as plotting, so if there are any changes then they
were errors before since plotting represents "truth".

jean-pierre charras 8085899d0a Pcbnew: better approximation of arcs by polygons for pads having a very small size.
Especially, small round rect pads have a ugly shape because the number of segments is
small and the 90 deg arcs are not very well approximated.
The minimal seg count for 90 deg arcs is now 4 (16 segm/circle) for pads.

Seth Hillbrand 6bcf1839b7 pcbnew: Add arc approximation setting to board
This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments.  This allows the user to customize their speed vs. accuracy
tradeoff.  The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.

This is mainly the solder paste layer that shows this issue.

jean-pierre charras d259459a14 Pcbnew: add a new primitive pad shape: chamfered round rect pad.
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.

jean-pierre charras 200ff1cda6 Pcbnew: Fix incorrect polygonal shape of thermal reliefs of rect pads.
Depending on thermal reliefs size, the polygons could be self intersecting,
and these self intersecting polygons are unexpected in zone calculations.
Other fix: the width of thermal stubs is clamped to the size of pads.
Previously, a bug in clamping calculations prevents constraining thermal stubs width.
