     When a container receives an expose event, it must send synthetic
     expose events to all children that don't have their own
     'GdkWindows'. This function provides a convenient way of doing
     this. A container, when it receives an expose event, calls
     'gtkContainerPropagateExpose'  once for each child, passing in the
     event the container received.

_U_s_a_g_e:

     gtkContainerPropagateExpose(object, child, event)

_A_r_g_u_m_e_n_t_s:

'object': ['GtkContainer']  a 'GtkContainer'

 'child': ['GtkWidget']  a child of 'container'

 'event': ['GdkEventExpose']  a expose event sent to container

_D_e_t_a_i_l_s:

     'gtkContainerPropagateExpose' takes care of deciding whether an
     expose event needs to be sent to the child, intersecting the
     event's area with the child area, and sending the event.

     In most cases, a container can simply either simply inherit the
     '"expose"' implementation from 'GtkContainer', or, do some drawing
      and then chain to the ::expose implementation from
     'GtkContainer'.
