Why does this small program cause an X11 BadMatch?

[Rich Burridge <Rich Burridge Sun COM>]

Hi all,

I've isolated the problem I'm seeing in converting an XView app to Gtk,
into the small example attached below.

Can somebody clue my in why this is outputting:

Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 36 error_code 8 request_code 62 minor_code 0

It's the:

    gdk_window_copy_area(xid, svgc, 0, 0, xid, 0, 0, width, height);
    
that's bitching. The source and dest values are the same so I'm guessing
it's something I've set in svgc (foreground/background?), but I'm not sure
what I should be setting them too here.

Thanks.
