Subject: [PATCH 1/2] widgets: always feather rounded-corner fills/borders

Drop the windowNaturalScale() >= 2.0 heuristic that skipped edge fade
on hi-dpi displays. It assumed pixel density alone hides aliasing, but
that only holds for straight edges - on real hi-dpi hardware, rounded
corners (any radius, not just small ones) still show visible aliasing
without the fade. Always feather now; ninepatch draws keep fade=0
since those already have their own baked edges.
