Deferred draw clip: resize queued · case 02

Queued coverage outside a resized target survives into flush.

Case contract

Submission captures coverage, enabled state and clip polarity at enqueue time. Flush emits queued draw samples in order and consumes the queue. Cancel removes matching draw IDs. Barrier flushes but does not reset clip state. A target resize clips queued samples to the new extent without expanding old snapshots.

Why this case matters

Raster clip state can leak coverage across draws even when every individual region is valid.
