* An autoplaying tetris mode for xlockmore

*
* Todo list:
* -Add option for the level of thinking the computer should perform
* (i.e. dummy = do nothing ..... genius = do always the best move
* possible)
* -Get welltris option to work better.
* draw more sophisticated squares (i.e. something like the bitmaps
* on tetris)
*
* Revision History:
* 01-Dec-2000: Lifted code from polyominoes for variable size pieces
* Copyright (c) 2000 by Stephen Montgomery-Smith
* 01-Nov-2000: Allocation checks
* 02-Aug-2000: alwelltris trackmouse implemented
* 27-Jul-2000: alwelltris all but trackmouse
* 22-Jun-2000: trackmouse added, row clearing fixed, bonus pieces,
* 01-Nov-1998: altetris additions by David Bagley
* 01-Oct-1998: Created
