gdk_window_get_internal_paint_info()

If you bypass the GDK layer and use windowing system primitives to
draw directly onto a GdkWindow, then you need to deal with two
details: there may be an offset between GDK coordinates and windowing
system coordinates, and GDK may have redirected drawing to a offscreen
pixmap as the result of a gdk_window_begin_paint_region() calls. This
function allows retrieving the information you need to compensate for
these effects.
