Function webrender::tile_cache::create_tile_cache

fn create_tile_cache(
    slice_flags: SliceFlags,
    scroll_root: SpatialNodeIndex,
    iframe_clip: Option<ClipId>,
    prim_list: PrimitiveList,
    background_color: Option<ColorF>,

Given a PrimitiveList and scroll root, construct a tile cache primitive instance that wraps the primitive list.
