- * 		* might be nice to move this over into terminal.c.
- * 		  That way we could check which palette entries in
- * 		  cfg have actually been _changed_ during
- * 		  reconfiguration, and only update those ones in
- * 		  the currently visible palette. Also it'd save
- * 		  some of this hassle in the next port.
- *           - enable/disable/move the scroll bar if necessary
- *           - change the window title if necessary
- *           - reinitialise the fonts
- * 	     - resize the window if necessary (may be required

- * 	       or both)
- *           - redraw everything, just to be safe.
- * 	  + In particular, among the above chaos, we must look into

- * 	    since the Unix default is to derive the latter from the
