Seth Hillbrand 035ff27b76 Be smarter about checking SHAPE_POLY_SET intersect
The segment iterator creates segments when needed, so using it in a dual
loop creates NlgN more copies than we need.  This shifts to a single
copy algorithm that then uses a sorting to preemptively abort the search
once the segments are outside of the search bounding box

jean-pierre charras ca2dde23d0 SHAPE_ARC::Collide(): fix incorrect returned position of colliding point.

jean-pierre charras 1047e7143a SHAPE_ARC::GetCentralAngle(): ensure a 360 deg arc angle is always returned as 360 deg.
An arc having the same start and end points can be 0 or 360 deg arc.
In Kicad it is always 360 deg arc (i.e. a circle)

Seth Hillbrand fcf44091d2 Ensure bad polys get simplified before triangulation
If the poly set is self-intersecting, the triangulation may be
problematic and the full set needs simplification before.  We don't do
this uniformly because the simplification can be a slowdown if it is not
needed

Seth Hillbrand 8e97855557 Fix Clipper2 handling of Inflate/Deflate
For unknown reasons, Clipper2 only returns Paths structures from the
ClipperOffset::Execute routine.  Further, the Paths are not properly
ordered (outline->hole in outline, outline2->hole in outline2).
To get proper hierarchy, we need to run an additional pass of the
solution with the paths as Subject in a null union.  This is effectively
a Simplify() call but we keep the data in Clipper format to reduce the
churn/calc time

Seth Hillbrand 546e16a002 Add multi-level fallback in tesselation
Some clipper cases do not get resolved with the `FAST` mode, so in those
cases, do a second pass in the `SIMPLE` mode.  If both fail, return a
broken polygon instead of an infinite loop

Seth Hillbrand 4cdf0bd6c9 Clipper2: Handle nested poly/hole/poly returns
In Clipper1, we had a flat tree structure on returns.  Clipper2 nests
these, so we need to properly handle the nesting structure when
importing the polygons

Seth Hillbrand 27add591ec Add Clipper2
Currently this lives behind the advanced config flag `UseClipper2`.
Enabling this flag will route all Clipper-based calls through the
Clipper2 library instead of the older Clipper.  The changes should be
mostly transparent.

Of note, Clipper2 does not utilize the `STRICTLY_SIMPLE` flag because
clipper1 did not actually guarantee a strictly simple polygon.
Currently we ignore this flag but we may decide to run strictly-simple
operations through a second NULL union to simplify the results as much
as possible.

Additionally, the inflation options are slightly different.  We cannot
choose the fallback miter.  The fallback miter is always square.  This
only affects the CHAMFER_ACUTE_CORNERS option in inflate, which does not
appear to be used.

Lastly, we currently utilize the 64-bit integer coordinates for
calculations.  This appears to still be faster than 32-bit calculations
in Clipper1 on a modern x86 system.  This may not be the case for older
systems, particularly 32-bit systems.

Jeff Young e5de56b6cc Fix edge case in arc collision.
SHAPE_ARC::IntersectLine() fails when one of the arcs start points
is on the center point of the other -- in this case we can't extend
the line to the arc intersection because one point does not define
a line....

Jeff Young 19d270fe74 Text size sanity checking for TEXT_ITEMS_GRID.
Oh dear, there was a bunch going on here.  Firstly the move from int
to long long int for ValueFromString() means that we were no longer
catching overflows (as we were C-style casting it back to int in many
places).  But even when the overflow is caught, it would run in to
wxWidgets' empty string bug while trying to log it.

2022-08-26 08:45:13 -07:00
Seth Hillbrand 06786c34d7 Blacklist hashes for 2d integer elements
The hash table for integer hashes is extremely limited and places most
elements in the same buckets.  This leads to a linear search time for
structures built on this.

This blocks hashes, directing the coder to utilize std::set or std::map
structures instead of hash tables for implementing integer-based
lookups.
