        Figured out how to make X close only one window (rather 
           then all the windows) when you clicked the close box with
           the mouse.
        Figured out how to trap broken pipe errors caused by severing
           X client/server connections.

		   is closed

	  Sun Mar 13 2005
	    Fixed problem with calculating default bitmap size
	   
	  Sun Mar 27 2005
	    Reorganized xs functions so that they are now alphabetical
	    Added (lame) support of drawing rotated text. Its not actually 
	      rotated, just drawn along a rotated baseline.
	    Added error handling to cursor so that if the user clicked on
	      the window and closed it all would not be lost.
