Tests compare native and enhanced masked pixels with unmasked images when
precise positions cross the integer bounds, including negative coordinates.
A tiny precise triangle must submit three row clips rather than 256.
Flat overlay rectangles also submit one-row geometry while field masking is
active. This keeps the mask when a wide backend intentionally replaces its
scissor. Non-interlaced overlays retain the original geometry and policy.
A backend fixture that ignores the scissor tests both field parities, original
progressive behavior, and clip restoration. This is not Vulkan driver testing.
