Fixed parameters for changed interfaces for WinHPCTask
Fixed missing closed property of OutStream class
Fixed call_tip placement for multi-screen setups

replaced width by right and height by bottom to check if call_tip is
within screen. E.g. my right screen gives back this screen-rect
QRect(1680, 0, 1600, 1200) (left, top, width, height), since my
main screen on the left has a width of 1680. Checking off-screen
now properly uses right (1680 + 1599) and bottom (0 + 1199) instead of
width and height.
