How to force a repaint of the content.



Q. What is the message to send to a VisContent which will make it
   repaint itself and its visual children? I am doing a lot of
   VUM_MANUAL things and want to repaint the content at the end of
   my routine. The message will be sent by an object running in my
   application thread.

A. Send MSG_VIS_VUP_UPDATE_WIN_GROUP with VUM_NOW (assuming that your
   VUM_MANUALs have invalidated things).
