Patch 0027: a float colour output turns NaN into 0 and clamps the rest to +-1e30 before it reaches its target, so one
bad texel cannot spread through bloom, blur and downsample passes as black or white blocks; integer targets keep their
bits. Task and mesh shaders start their mesh and primitive counts at 0 behind a barrier, and a task emits at most one
mesh group per thread, so a task that culls everything no longer launches what the shared memory last held. Without a
gamepad SDL can open, the first connected XInput controller (slots 0-3, empty slots asked once a second) is read
directly. Kokiri Forest: 60 fps, GPU 5.5 ms a frame, unchanged.
