Nest windows now rerun the overlap check once the layout has been
unchanged for 0.5 s, instead of leaving 'Overlaps: not checked'. Edits
show 'Overlaps: check pending...'; drags are caught by the paint-time
pose stamp, collection edits by their events. The check waits while a
mouse button, modal dialog or fill is active, supersedes a running check
when the layout moves again, and does not retry a canceled or failed
layout until it changes. Rechecks use the incremental analyzer, so only
the moved parts' neighbors are recomputed.
Automatic results update only the canvas label (the status bar keeps the
last command's message) and keep Display > Off. Check Active Plate still
runs immediately. InvalidateOverlapCheck now also drops cached material.
A straight lead-in at a convex outside-perimeter corner now runs along the
extension of the edge cut first, so the torch enters on that line and keeps
cutting it. The result no longer depends on which of the corner's two edges
auto-assign or the manual cursor picked, which made placement flip between
straight and 90 degrees. The approach angle is ignored at such corners.
The straight lead falls back to the first-cut edge normal when its pierce
would be closer than PierceClearance to the contour (very flat or tessellated
corners). Reflex perimeter corners bisect the notch. Line lead-outs run on
straight past a convex corner along the last-cut edge, except on tabbed
perimeters. Program generation and the Place Lead-in preview share
ResolveLeadIn/ResolveLeadOut.
