Nicer function for drawing text in 3d window:

ED_region_visible_rect(ar, rect)
Returns the visible rect inside a region, subtracting the overlapping UI regions.

Added with minimal overhead, only called once per region draw.

Also fixes the 'Auto Key' warning print in 3d window (was behind properties)
