Currently, in CPU painter, border painting is implemented by building a Gfx::Path that is filled by Gfx::AntiAliasingPainter. In the GPU painter, we will likely want to do something different, and with a special command, it becomes possible. Also, by making this change, the CPU executor also benefits because now we can skip building paths for borders that are out of the viewport.
