Mouse
ms.pos.x and ms.pos.y can be used to access the x and y coordinates of the 
mouse.  They are relative to the scrn, not window.  These can be used if you 
don't want to use msg passing.  ms.pos.z is the wheel.

ms.pos_text.x and ms.pos_text.y are the text column and row.  See 
::/Demo/Games/Maze.HC.

See CMsStateGlbls and CMsHardStateGlbls.

The hard designation, as in ms_hard, represents hardware layer items before the 
application of an abstraction layer.
