Stencil write mask preserves bits · case 05
Masking only the new stencil value clears protected existing bits.
Case contract
Old/new/mask are bytes. Replace only stencil bits enabled by the write mask; preserve every masked-off old bit.
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
