[XGP-announce] XGP 0.3.0

[Lindsey S. <sp...@al...>]

XGP 0.3.0 is now available at
http://xgp.sourceforge.net/

Changes from release 0.2.1 to 0.3.0:

	* Support for recognizing presence of Mac line endings
	when loading a document (\r) and giving the user the choice of
	auto-converting the document to UNIX line endings (\n).

	* Added support for new/[2,3,4] and old/[2,4] predicates.

	* New window builtin--actdeact/2: window events of becoming main,
	resigning main, and closing trigger invocation of a
	specifiable "handler" predicate.
		
	* New builtins for the graphics system:
	
		- Utility builtin--equivalent_pics/2.
		- Graphics window--gmax/3, refresh_now/1, scroll_by/3,
		reverse_pics/1, bring_to_front/2, send_to_back/2.
		- Shifting, changing, and renaming graphic
		items--shift_pic/3, shift_pics/3, chg_pic/3, rename_pic/3.
		- Retrieving, deleting, selecting, and deselecting
		graphic items--get_pic/[3, 4], del_pic/2, del_all/1,
		del_pic_num/2, del_sels/1, sel_pics/2, sel_all/1,
		get_sel_pics/2, desel_pics/2, desel_all/1, get_desel_pics/2.
		
	* Implemented a "Check for New Version of XGP" service,
	with auto-check-on-open preference.

	* Better support for multiple Evaluate Query dialogs:
	They are uniquely named and are in the Windows menu.

	* Extended control window 'menu' item to support
	hierarchical menus. Fixed a bug in handling
	strings in cw_get_item.

	* Fixed graphics system bugs in:
	
		- setting the origin of a textline graphic item.
		- pic_frame's handling of 'scale' transformer.
		- drawing 'scale' and 'trans' transforms (bounds of the
		translated graphic item weren't being properly calculated).
		- closing a graphic document (was causing XGP to crash).

	* Fixed other bugs in:
	
		- handling of UTF8 for source files generally,
		and specifically reading non-lower-ASCII characters.
		This caused consulting a source window to fail with a
		spurious syntax error.
		- banner/4 and dialog/8 to ensure that their created control
		windows have unique names.
		- multiple simultaneous openings (the associated
		simultaneous consults were sometimes failing).
		- low-level document handling.
