+ * @short Widget on which video is displayed by DSA rendering
+ *
+ * This implementation is used on devices with the legacy graphics
+ * subsystem, which does not support surfaces.  On such devices,
+ * video rendering is done via Direct Screen Access (DSA), whereby
+ * the video decoder writes directly to the framebuffer.  To ensure
+ * that the window server and video decoder do not try to draw to
+ * the same screen region at the same time, the video subsystem
+ * first requests permission to perform DSA.  If the window server
+ * needs to draw to this screen region (for example to display a
+ * message dialog), it first notifies the video subsystem that it
+ * must stop rendering to this region.
+ *
