     // relative to the client bounding box, and it gets captured in the cached Pattern shader.
     // Hence, we need one Pattern shader per client. The display list OTOH is the same => we
     // should be able to cache a single display list per LayoutSVGResourcePattern + one
     // Pattern(shader) for each client -- this would avoid re-recording when multiple clients
     // share the same pattern.
