[screenlocker] Cleanup in LockWindow
Review Request #124929 - Created Aug. 26, 2015 and submitted
It set to arrow cursor which is the default anyway. [screenlocker] Drop setting event mask on the background window We don't need it as we get keyboard and pointer events anyway (grab), exposure is set by Qt anyway and for everything else we have substructure redirect on the root window. Setting the background pixel is also no longer needed: we render a black, non-translucent window. [screenlocker] Rename LockWindow to X11Locker The LockWindow is no longer a window, but it's the actual locker for X11.
