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.
