462 :     - Toggle and button protocol has changed. Command and toggle buttons
463 :     register a change on button up, not on button down. If button up
464 :     occurs off the widget, no change is registered. Event streams for
465 :     general buttons now terminate with either button up or exit, the latter
466 :     indicating the mouse has left the widget. Buttons and toggles also now
467 :     provide active/inactive state.

473 :     GLOBAL CHANGES:
474 :     - eXene is now based on CML-0.9.4; this very required minor changes to
475 :     eXene (now using 0.9.6).
476 :    
477 :     - ported to SML/NJ 0.71. Most changes were a result of the Array structure
478 :     not being open by default, and by Array.sub no longer being an infix operator.
479 :     Changed the representation of pen_t values to use immutable vectors.
480 :    
481 :     LIBRARY CHANGES
482 :     - fixed typechecking problem in protocol/xdisplay.sml that was exposed
483 :     by SML/NJ 0.70.
484 :    
485 :     - replaced draw_dst_t datatype with abstract drawable_t type. This is
486 :     part of the support for rubber-banding.
487 :    
488 :     - fixed xio.sml bug caused by a faulty understanding of the sequencing
489 :     semantics of the protocol.
490 :    
491 :     - fixed bugs in gc-server.sml and draw-master.sml reported by Huimin Lin
492 :     (huimin@@cogs.susx.ac.uk).
493 :    
494 :     - fixed bug in HashUtil.mapList
495 :    
496 :     - changed remove function for hash tables to return the removed item. This
497 :     affected the hash tables defined in util/{hash-util.sml,hash-xid.sml},
498 :     window/hash-window.sml and user/eXene-base.sml.
499 :    
500 :     - added window-tree locking mechanism to the window registry.
501 :    
502 :     - modified asynchronous blt operations to use a promise-style implementation.
503 :    
504 :     - added updatePen operation for functional updates of pens.
505 :    
506 :     - added createOverlay to support rubber-banding.
507 :    
508 :     - new Spline module providing functions to compute Bezier cubic sections,
509 :     and open and closed B-splines.
510 :    
511 :     - added copyBlt and copyBltEvt.
512 :    
513 :     - fixed bug in decoding font info in xreply.sml (wrong offset)
514 :    
515 :     WIDGET CHANGES
516 :     - fixed possible deadlock arising from parent not always servicing a child's
517 :     CO event. This affected box.sml and field-edit.sml.
518 :    
519 :     - added new text list widget. The widget provides a vertical or horizontal
520 :     display of text items, and events associated with the user choosing items.
521 :    
522 :     - the ButtonView structure now provides a new view mkTextBtn, which
523 :     generalizes mkLabelBtn (rectangular buttons with string labels) by
524 :     allowing the programmer to specify the border width and text alignment
525 :     within the button.
526 :    
527 :     - fixed bug in Frame widget that was causing deadlock.
528 :    
529 :     - the SimpleMenu module has seen various bug fixes and style
530 :     changes, as well as the addition of a low-level menu routine
531 :     for providing pop-up menus within widgets.
532 :    
533 :     - there is now a working vtty widget (thanks to Thomas Yan for finishing
534 :     our code)
535 :    
536 :     - the Canvas widget now provides a drawable, so that the library drawing
537 :     routines can be used.
538 :

550 :     Also, the PV_Exposures field for pens has been eliminated.
551 :    
552 :     - destroyWindow is now handled by the draw-master, which avoids a race
553 :     with any pending drawing requests on the window. This was a problem
554 :     with popup windows.
555 :    
556 :     - added Geometry.inside; test if a rectangle is inside another
