Chooses the frame based on the start time passed to
gdk_pixbuf_animation_get_iter().
@current_time would normally come from g_get_current_time(), and
must be greater than or equal to the time passed to
gdk_pixbuf_animation_get_iter(), and must increase or remain
unchanged each time gdk_pixbuf_animation_iter_get_pixbuf() is
called. That is, you can't go backward in time; animations only
play forward.
As a shortcut, pass NULL for the current time and g_get_current_time()
will be invoked on your behalf. So you only need to explicitly pass
@current_time if you're doing something odd like playing the animation
at double speed.
If this function returns FALSE, there's no need to update the animation
display, assuming the display had been rendered prior to advancing;
if TRUE, you need to call gdk_pixbuf_animation_iter_get_pixbuf()
and update the display with the new pixbuf.
Possibly advances an animation to a new frame.
