Struct PictureScratch 

pub struct PictureScratch {
    pub primary_render_task_id: Option<RenderTaskId>,
    pub secondary_render_task_id: Option<RenderTaskId>,
    pub extra_gpu_data: SmallVec<[GpuBufferAddress; 1]>,
}

Per-frame scratch data for a Picture primitive. Pushed in take_context and read by both prepare and batch through the scratch_handle carried on PrimitiveKind::Picture.

Fields

primary_render_task_id: Option<RenderTaskId>

All render tasks have 0-2 input tasks.

secondary_render_task_id: Option<RenderTaskId>

If a mix-blend-mode, contains the render task for the readback of the framebuffer that we use to sample from in the mix-blend-mode shader. For drop-shadow filter, this will store the original picture task which would be rendered on screen after blur pass. This is also used by SVGFEBlend, SVGFEComposite and SVGFEDisplacementMap filters.

extra_gpu_data: SmallVec<[GpuBufferAddress; 1]>

Optional cache handles for storing extra data in the GPU cache, depending on the type of picture.
