pub const SCREEN_WIDTH: usize = 256;Expand description
Visible screen width in pixels, and the stride of every per-pixel buffer the PPU exposes.
v2.3.8 — the single definition. provenance::SCREEN_W was a second copy of
this number in a debug-hooks-gated module, which made the width
unreachable from ungated code and invited a third copy rather than a
dependency. It now aliases this.
