Stencil increment saturates · case 04
Stencil increment wraps a saturated 255 value back to zero.
Case contract
Increment a stencil byte using the saturating increment operation, distinct from increment-and-wrap.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
One recorded failure
