"Length" is more natural than "height" for flat plate materials.
Renames the field on OpenNest.Geometry.Size, Box.Height property,
and all references across 38 files.

DXF files can have endpoint gaps at entity junctions that fall right at
the floating-point boundary of Tolerance.Epsilon (0.00001). This caused
shapes to not close, resulting in 0 area and 0% utilization in Best-Fit.
Added ChainTolerance (0.0001) for endpoint chaining in GetConnected and
Shape.IsClosed, keeping the tighter Epsilon for geometric precision.

The push algorithm's copy distance formula (bboxDim - slideDistance)
produced distances smaller than the part width when inflated boundary
arc vertices interacted spuriously, causing ~0.05 unit overlaps between
all adjacent grid parts.
Two fixes applied:
- Clamp ComputeCopyDistance to bboxDim + PartSpacing minimum
- Use circumscribed polygons (R/cos(halfStep)) for PartBoundary arc
discretization so chord segments never cut inside the true arc,
eliminating the ChordTolerance offset workaround
Also parallelized three sequential fill loops using Parallel.ForEach:
- FindBestFill angle sweep (up to 38 angles x 2 directions)
- FillPattern angle sweep for group/pair fills
- FillRemainingStrip rotation loop
Added diagnostic logging to HasOverlaps, FindCopyDistance, and
FillRecursive for debugging fill issues.
Test result: 45 parts @ 79.6% -> 47 parts @ 83.1%, zero overlaps.

Opposite hull edges (180° apart) produce identical bounding rectangles
(width/height swapped), so only half the edges need to be checked to
find the minimum area. Applied to the unconstrained overload only.

- Add bounding box rejection in HasOverlaps to skip expensive
Part.Intersects (CNC→geometry conversion) for non-adjacent parts.
Eliminates ~35% CPU in IsBetterValidFill for grid layouts.
- Optimize RayEdgeDistance: access Line fields directly instead of
property getters (avoids Vector struct copies), inline IsEqualTo
with direct range comparison (avoids Math.Abs), and precompute
deltas for reuse in interpolation.
- Cache line endpoints in DirectionalDistance outer loop to avoid
repeated struct copies in the inner loop.
- Add fill timer to ActionClone.Fill, displayed in PlateView status
bar as "Fill: N parts in M ms".

Add LineTypeName to Layer and propagate resolved color/line-type
through all DXF entity conversions (Arc, Circle, Line, Spline,
Polyline, LwPolyline, Ellipse). Entities that inherit ByLayer
properties now correctly resolve to their layer's values.

Add per-entity IsVisible flag and wire up the Colors and Line Types
checkedlistboxes to filter entities by exclusion — checking an item
hides matching entities from the preview and from drawing export.

Polygon offset at concave corners creates geometry that folds back
through itself. Added RemoveSelfIntersections() to Polygon that
detects non-adjacent edge crossings and removes the smaller loop
at each crossing. Applied to both collision detection and rendering.

SetRotation always forced CW regardless of the requested rotation,
so cutouts (which should be CCW for kerf-left) were also set to CW.
Now uses the rotation parameter to set the correct winding direction.
Also reverts the Shape.OffsetEntity cutout side inversion since the
correct fix is proper winding from the converter.

Cutouts wind opposite to the perimeter, so using the same OffsetSide
expands holes instead of shrinking them. Invert the side for cutouts
so the offset buffer correctly contracts holes inward.

Add SegmentsForTolerance(double) to Arc and Circle that calculates the
minimum segments needed to keep sagitta within the given tolerance.
Add Shape.ToPolygonWithTolerance() that uses it per arc/circle.
Push distance now uses 0.08" chord tolerance instead of a fixed segment
count, giving appropriate resolution for each arc based on its radius.
