cutealien 0368c5b09d IGUIEnvironment::drawAll has now a parameter to allow disabling the automatic resize to driver screensize.
That makes it easier to use partial screens, while using automatic alignment. 
Default is still automatic resizing as before, thought it got changed a bit as it looked a bit strange.
Before it only set the lower-right corner, but compared to driver screensizes, so it behaved a bit strange
when the leftTop corner of the rootGuiElement was changed (different than when the rightBottom corner was set).
Could be the idea before was that only clipping matters.
