* This struct allows us to inform the client how many "widthBytes"
* that we need. Note that we use the new idea of "widthBytes"
* because this idea is distinct from "rowBytes" (used elsewhere in
* Skia). "rowBytes" allow the last row of the allocation to not
* include any extra padding, while, in this case, every single row of
* the allocation must be at least "widthBytes".
