I need some help with regard to working with metafiles.  I am trying to
output a report that includes fonts and graphics to 3 devices: client window,
default printer, and disk file.  To create the report, I am first writing
the information to a metafile I get from the function CreateMetaFile().

The problem that I am encountering is when I try to display it on the
OWL client window.  To display it, I am overloading the TWindow::Paint()
member function.  In this function, I am calling the function PlayMetaFile().
This works fine for shorter metafiles.  But for very long metafiles, when
I have to scroll the client window, it takes a very very long time to 
execute the TWindow::Paint() member function.

Is there any way to control the play back of the metafile so that it only
paints the portion that would be visible within the client window?

thanks in advance,
