On Cocoa the full-bitmap alpha-restore pass is unnecessary: Canvas
operations keep alpha at $FF and the cached grid background is opaque,
so removing it cuts a full-frame O(W*H) pass per spectrum frame with no
visual change (verified on macOS).
Kept under {$IFNDEF DARWIN} for Qt6/win32 (different drawing backends
may zero alpha on antialiased edges) until visually verified there.
