python test case

for my app i used to grab screenshots of other windows without problems.
somewhere wine>1.2 it stopped working as expected. screenshots now show black
areas as if desktop size was too small. a window placed top/left of the desktop
gets grabbed, the more the window is moved to bottom/right the less gets
grabbed.
reproducable in Qt4 as well. QPixmap::grabWindow() leads to the same result.

attatched a test case (python)

fire up notepad and run the test. a file "test.bmp" should get dumped to
current dir containing a screenshot of notepad.
