I wish to send an exposure event to my app, without touching the screen
(no ClearWindow e.g.).
Earlier I tried GrClearArea (wid,0,0,0,0,1); and I think that worked on
a window, but now I use GR_ROOT_WINDOW_ID for all graphics, and
ClearArea just don't work. It sends a exposure event, but still clears
the whole screen!
Are there any way I can just send an exposure event to an app? Like
InvalidateRect on Win32 GDI.
