The previous commit's no-region fallback never fired: gamescope DOES
advertise a region — (0,0,INT32_MAX,INT32_MAX), meaning "coordinates
are raw". Mapping normalized positions into it explodes a center tap
to x≈1e9, clamped by gamescope to the far corner — the cursor pinned
at (1279,799) and every degraded-touch tap landing there. Treat a
region as an output geometry only when plausibly sized (≤16384 px);
otherwise emit raw client pixels.
