- Regenerate cut-off programs after RotateSelectedParts so cut lines
update when parts are rotated, not just moved
- Change default CutDirection from TowardOrigin to AwayFromOrigin so
cuts start at the origin axis

- Extract MakePoint/AxisBounds/CrossAxisBounds helpers in CutOff to
eliminate repeated axis-dependent branching
- Simplify BuildProgram loop from 4 code paths to 2
- Use static EmptyExclusions to avoid per-part list allocations
- Fix double event subscription in ActionCutOff constructor
- Dispose debounce timer in DisconnectEvents
- Remove redundant BuildPerimeterCache call in OnMouseDown
- Extract TotalCutLength test helper, remove duplicate test

Replace CutOff.BuildPerimeterCache (List<Shape>) with Plate.BuildPerimeterCache
(Dictionary<Part, Entity>) throughout. Consolidate two Regenerate overloads into
a single method with optional cache parameter. Fix Shape intersection bug where
non-intersecting entities added spurious Vector.Zero points to results.

CutOff computes cut segments along a vertical or horizontal axis,
excluding zones around existing parts with configurable clearance.
CutOffSettings controls part clearance, overtravel, minimum segment
length, and cut direction (toward/away from origin).

Extract distance computation from RotationSlideStrategy into a pluggable
IDistanceComputer interface. CpuDistanceComputer adds leading-face vertex
culling (~50% fewer rays per direction) with early exit on overlap.
GpuDistanceComputer wraps ISlideComputer with Line-to-flat-array conversion.
SlideOffset struct uses direction vectors (DirX/DirY) instead of PushDirection.
SpatialQuery.RayEdgeDistance(dirX,dirY) made public for CPU path.

Three bugs fixed in NfpSlideStrategy pipeline:
1. NoFitPolygon.Reflect() incorrectly reversed vertex order. Point
reflection (negating both axes) is a 180° rotation that preserves
winding — the Reverse() call was converting CCW to CW, producing
self-intersecting bowtie NFPs.
2. PolygonHelper inflation used OffsetSide.Left which is inward for
CCW perimeters. Changed to OffsetSide.Right for outward inflation
so NFP boundary positions give properly-spaced part placements.
3. Removed incorrect correction vector — same-drawing pairs have
identical polygon-to-part offsets that cancel out in the NFP
displacement.
Also refactored NfpSlideStrategy to be immutable (removed mutable
cache fields, single constructor with required data, added Create
factory method). BestFitFinder remains on RotationSlideStrategy
as default.

ConvexMinkowskiSum is O(n+m) with no boolean geometry ops.
The concave Minkowski path was doing triangulation + pairwise
sums + Clipper2 Union, which hung at 100% CPU for complex parts.

Add immutable Translate methods to Box. Make NoFitPolygon
ToClipperPath/FromClipperPath public with optional offset parameter.
Refactor InnerFitPolygon.ComputeFeasibleRegion to accept PathsD
directly, letting Clipper2 handle implicit union. Add UpdateBounds
calls after polygon construction.

CloneAtOffset shares the Program instance for tiling performance,
but rotating a part on the plate mutated the shared Program, causing
all parts from the same tile template to rotate together.
Added ownsProgram flag with EnsureOwnedProgram() that clones the
Program before first mutation, preserving tiling performance while
making user rotations independent.

Kept using OpenNest.Api in Timing.cs and EditNestForm.cs alongside
remote's reorganized usings and namespace changes.

Relocates CutParameters from OpenNest namespace to OpenNest.Api, adds
LeadInLength and PostProcessor properties, and provides a typed Default
factory. Updates Timing.cs, the WinForms project reference, and the three
consuming forms to resolve the type from the new namespace.

Add Vector-based overloads to SpatialQuery (ray casting, edge distance,
directional gap, perpendicular overlap) and PartGeometry (directional
line filtering) to support pushing parts along any angle, not just
cardinal directions.
Add Compactor.PushBoundingBox for fast coarse positioning using only
bounding box gaps. ActionClone shift+click now uses a two-phase strategy:
BB push first to skip past irregular geometry snags, then geometry push
to settle against actual contours.

The Size fix (d4222db) changed Size.Width to Y axis and Size.Length to
X axis but only updated DrawPlate/LayoutViewGL. BoundingBox, WorkArea,
rotations, DXF export, and engine code still used the old Width=X
convention, causing the fill engine to get a swapped work area (60x120
instead of 120x60) and parts to fill in the wrong direction.

FlangeShape generates an outer circle with evenly-spaced bolt holes
on a bolt circle pattern. ShapeDefinition.LoadFromJson<T>() provides
generic JSON loading for any shape — no separate preset classes needed.

Size.Parse and ToString now use WxL format (width first) matching the
natural convention. Fixed the Plate(w,l) constructor which was swapping
args when creating Size. Fixed PlateView.DrawPlate and DrawControl
ZoomToArea which had width/length mapped to the wrong screen axes.
Simplified Console --size parsing to use Size.TryParse instead of manual
split with confusing PlateHeight/PlateWidth fields. Added Command-Line
Interface section to README documenting all console options.

Use pole-of-inaccessibility (polylabel) to place part labels at the
visual center of shapes instead of the first path vertex. Labels now
stay correctly positioned regardless of part rotation or shape.
Also adds project README and MIT license.

Extract direction helpers to Helper class (EdgeDistance, DirectionalGap,
DirectionToOffset, IsHorizontalDirection) and use them to skip parts not
ahead in the push direction or further than the current best distance.
Defer line computation until parts survive bounding box checks.

The BestFitFilter's aspect ratio cap of 5.0 was rejecting valid pair
candidates needed for narrow plates (e.g. 60x6.5, aspect 9.2) and
remainder strips on normal plates. Three fixes:
- BestFitFinder: derive MaxAspectRatio from the plate's own aspect
ratio so narrow plates don't reject all elongated pairs
- SelectPairCandidates: search the full unfiltered candidate list
(not just Keep=true) in strip mode, so pairs rejected by aspect
ratio for the main plate can still be used for narrow remainder
strips
- BestFitCache.Populate: skip caching empty result lists so stale
pre-computed data from nest files doesn't prevent recomputation
Also fixes console --size parsing to use LxW format matching
Size.Parse convention, and includes prior engine refactoring
(sequential fill loops, parallel FillPattern, pre-sorted edge
arrays in RotationSlideStrategy).
