ConvertMode.ToIncremental skipped SubProgramCall codes entirely when
computing deltas, so parent motions after a sub-call were encoded as if
the tool never moved. Several traversal sites (ConvertProgram,
GraphicsHelper, PlateRenderer, CutDirectionArrows, Program.BoundingBox)
worked around this with save/restore hacks that treated sub-calls as
transparent — but DrawRapids legitimately tracks actual tool position,
so after the last hole the first perimeter rapid was applied to the
wrong base, drifting the rendered perimeter past the plate edge by
roughly the distance to the last hole.
Fix the root cause: ToIncremental and ToAbsolute now walk sub-programs
to compute where they leave the tool, and advance pos accordingly. The
other traversals capture a frameOrigin at entry and compute sub-call
placement as frameOrigin + Offset, letting pos advance naturally
through the sub recursion. All the save/restore workarounds are
removed.
Program.BoundingBox also picks up the same frame-origin treatment,
which corrects a latent bug where absolute-mode endpoints and nested
sub-calls dropped the parent's frame origin.

ConvertMode.ToIncremental skips SubProgramCalls when computing deltas,
so all code paths that expand SubProgramCalls must: (1) set curpos to
savedPos + Offset before expanding, and (2) restore curpos afterward
so subsequent incremental codes get correct deltas.
Fixed in ConvertProgram, GraphicsHelper (AddProgram, AddProgramSplit),
PlateRenderer (DrawRapids, DrawProgramPiercePoints, GetFirstPiercePoint),
and CutDirectionArrows.

Inline sub-program geometry into the parent geometry list using Offset
as the starting curpos, replacing the Shape-wrapping approach.

Circle.Rotation was lost in three places, causing reversed circles to
still offset inward instead of outward:
- ConvertGeometry.AddCircle hardcoded CCW instead of using circle.Rotation
- ConvertProgram.AddArcMove created Circle without setting Rotation from arc
- Shape.OffsetOutward/OffsetInward copied Circle without setting Rotation

ConvertProgram.ToGeometry() created entities without setting Color,
defaulting to Color.Empty (alpha=0). After ededc7b switched from
Pens.White to per-entity colors, these rendered fully transparent.
- Add explicit colors to all SpecialLayers (Cut=White, Rapid=Gray, etc.)
- Set entity Color from layer in ConvertProgram for lines, arcs, circles
- Add GetEntityPen fallback: treat Empty/alpha-0 as White
- Add bend line rendering and selection in EntityView/CadConverterForm
- Fix SolidWorksBendDetector MText formatting strip for bend notes
