No, it can be anywhere.  But callbacks.c is the common place.

1.  write a timeout function that repaints the drawing area, returning
true or false depending on whether you want it repeated,

2.  write a callback function that is called when the drawing area
widget is created and mapped, which calls gtk_timeout_add(), passing the
pointer to the timeout function above.

gtk_main() will sleep until time expires, then it will call the timeout
function, then it will go back to sleep.  gtk_main() is also woken by
incoming events from the X display.
