/* The hardware supports two different modes for border color. The

 * legacy mode uses 4 bytes.
 *
 * More significantly, the legacy mode respects the components of the
 * border color for channels not present in the source, (whereas the
 * default mode will ignore the border color's alpha channel and use
 * alpha==1 for an RGB source, for example).
 *
 * The legacy mode matches the semantics specified by the Render
 * extension.
