Subject: LOK: setClientZoom() - sets the client zoom level

We need to know the client's view level to correctly handle the mouse
events in calc. PaintTile() set a zoom level that corresponds to the
requested tiles and previously postMouseEvent would call SetZoom(1,1).
Now we can make use of knowing the client's view level and call
SetZoom() with the correct parameters
