2014-09-20-12.52.34: src/lib/std/2d/geometry2d.pkg: Renamed lowerright -> lowerright1, added new lowerright.  Difference is that  lowerright returns  { col => box.col + box.wide - 1,  row => box.row + box.high - 1 } but lowerright1 returns  { col => box.col + box.wide,  row => box.row + box.high }.
