+/* The SyncSharedPixmap hook has two purposes:
+ *
+ * 1. If the master driver has it, the slave driver can use it to
+ * synchronize the shared pixmap contents with the screen pixmap.
+ * 2. If the slave driver has it, the master driver can expect the slave
+ * driver to call the master screen's SyncSharedPixmap hook, so the master
+ * driver doesn't have to synchronize the shared pixmap contents itself,
+ * e.g. from the BlockHandler.
+ *
+ * A driver must only set the hook if it handles both cases correctly.
+ *
+ * The argument is the slave screen's pixmap_dirty_list entry, the hook is
+ * responsible for finding the corresponding entry in the master screen's
+ * pixmap_dirty_list.
