/* 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.
