Struct PrimitiveScratchBuffer 

pub struct PrimitiveScratchBuffer {
    pub frame: PrimitiveFrameScratch,
    pub scene: PrimitiveSceneCache,
    pub retained: PrimitiveRetained,
}

Contains various vecs of data that is used only during frame building, where we want to recycle the memory each new display list, to avoid constantly re-allocating and moving memory around. Written during primitive preparation, and read during batching.

Storage is partitioned by lifetime: frame is per-frame (cleared in begin_frame), scene is per-scene (recycled on scene rebuild), and retained lives across both with its own trim policy.

Fields

frame: PrimitiveFrameScratch

scene: PrimitiveSceneCache

retained: PrimitiveRetained
