- Hybrid rasterizer: PIL scanline fill for the bulk, with cells in a
~2 px band around each ring edge re-tested exactly against the
polygon - cell-for-cell identical to the old center-in-polygon pass
(equivalence test added) but O(vertices + cells) instead of
O(vertices x cells). Measured 4.5 s -> 0.11 s at 1.45M cells with
8.8k polygon vertices.
- AMG-preconditioned CG (pyamg, new requirement) above 500k unknowns:
measured 7.0 s vs 15.3 s spsolve at 1.4M unknowns at a fraction of
the memory, R identical to 1e-6; the old Jacobi-CG (kept as fallback
when pyamg is missing) needed tens of minutes there. spsolve stays
the default below 500k where it is exact and fastest.

The intro predated the skin-effect feature; the AC capability was only
mentioned under Model & limits.

Open saved figures via xdg-open/open/startfile when no GUI backend
exists, and extend the potential map's color range below the V- mean
reference instead of clipping it.

The previous 24 px icons were a copper square with a tiny knocked-out
ohm that was unreadable in the toolbar. tools/gen_icons.py renders the
glyph supersampled from DejaVu Sans Bold in theme-specific copper
shades (plus the 64 px PCM listing icon).

- Refuse the uniform contact model when the fills form multiple
disconnected copper groups that each touch both terminals: the
prescribed injection split is ill-posed and the grounded system was
singular, silently returning garbage (e.g. negative gigaohms).
connected_restrict now reports the component count; a power-balance
backstop (SolverError) catches any other inconsistent solve.
- Connect via/pad barrels to the nearest fill copper within the pad
footprint (+1 cell) instead of only the exact center cell, so
thermal-relief spokes still stitch layers; barrels that reach fill on
fewer than two layers are warned about. ViaLink gains pad_nm
(extracted from the padstack, JSON-roundtripped).
- Validate dialog input on OK (layers, current > 0, cell > 0, parseable
frequency, extra Cu >= 0) with an inline error instead of silently
substituting defaults; parse_frequency raises on garbage; pipeline
rejects i_test <= 0; choose_cell_size rejects non-positive overrides.
- Warn when a contact part is dropped by the connectivity restriction;
floor instead of truncate in cell_of; correct the uniform-model
summary line; drop an unused variable; refresh plugin.json wording.
