If the objects use the standard properties interface, you don't really need
a new callback ; have a timer handler get the events, and apply them through
the property interface to the objects.[*] Presto ! You may have to call
ddisplay_add_updat() on the modified objects' rects, and a ddisplay_flush() to
have the window repainted the next time there's nothing better to do.

[*] In fact, that'd also work when these objects use older or specific
interfaces, your timer handler would just need to know how to specifically
talk to these.
