Version 2.1	11 March 1994
	Fixed a bug in Itemization processing (TextLayout.c).

	Restored rasterWidth and rasterHeight resources (these are just
	read only, setting them has no effect) into Raster.

	In TextEd.c use direct calls to Redisplay (expose method) instead
	of going trhough the server by XClearArea with expose request.

	In Text.c inverted attribute is now implemented by flipping the
	current background/foreground colors for the text (even if uglier,
	because spaces don't get inverted, it is at least consistent when
	applied to the colored text). There is still a lot of flicker when
	the widget is resized.

	Use ColorQuantize_FAST for non-JPEG images, if JPEG has been
	requested (used PPMQUANT before). Treat XeColorMode_NONE as if
	XeColorMode_COLOR was requested.

	Add exposeCallback resource into Basic. A test implementation
	support in XeBasic, XeRaster, XeText, XeTextEd and XeVideo widgets.
	(XeBasic can now be used a bit like blank drawing area, for other
	widgets the callback is made after all widgets own expose processing
	has been made).

Version 2.0	1 March 1994
	Widget set documentation updated to the current level of
	implementation.

	In TextFont.c the max number of fonts queried from the server
	has been increase from 1000 to 2000. This is still temporary
	solution, this should be application resourse or at least something
	the user can change and not a hardcoded constant.

	Resources colormapUse, colormapInstall, maxColors, colorQuantize
	and visual have been move to Basic class and from Raster. New
	resources rotation, mirrorImage, colorMode and useShm added. The
	enumeration names and strings for colorQuantize have been changed
	from the previous version (see the documentation).

	In Basic.c, the file to flow handling didn't work if feed
	function told to hold all buffered data (that is, feed didn't
	accept anything). fixed.

	Sample Video widget implementation using Berkeley MPEG decoder.
	
	The support hooks for the tagged text applications added into
	XeText and XeTextEd. A new callback resource XtNlayoutCallback
	and two callback reasons associated with it have been defined:
	XeCR_LAYOUT_CHANGE_TAG and XeCR_LAYOUT_BEGIN_LINE. Both callbacks
	use XeTextLayoutCallbackData. LAYOUT_CHANGE_TAG callback is generated
	when the layout process passes over a change of tags.
	LAYOUT_BEGIN_LINE is generated at the beginning of each line box.
	In both callbacks the application can insert layout content at that
	point into the layout process. The inserted layout content can
	contain any text and controls, all normal ISO 2022 and ISO 6429
	controls can be used. User cannot edit layout content and it
	is not exported to selections or cuts. Tagged data can be
	inserted programmatically using the function
	XeTextReplaceTagged and extracted using the function XeTextExtract.

	Initial state processing changed. The text.init field from the
	Text widget record has been removed.

	In XeText the itemization resource value is made local to the
	widget instance (the pointed value is copied, instead of
	using the pointer directly). XeAlignment_NONE added to the
	XeAlignment enumeration to be used as default/none indicator.

	Purify revealed memory leaks and reads referencing past
	allocated memory fixed (Raster24to8.c, RasterLayout.c and
	TextLayout.c)

	XeCvtHorizontalDimension changed into XeCvtHorizontalValue to
	allow signed values.

	New control sequences: RS (for Paragraph marker), JFY and QUAD
	from ISO 6429 experimentally implemented. The support for Paragraph
	concept: A new 'endseq' type Snip_EndParagraph has been added.
	It works exactly the same as Snip_EndLine, except addition it
	re-enables the first-line-offset and itemization processing for
	the next line. On input, RS (ctrl-^) converted to EndParagraph
	sequence, and if COMPOUND_TEXT export is enabled, it is exported
	as RS; on STRING two LF's is used instead.

Version 1.5	30 Oct 1993
	Vendor.c removed from the package. The presense of it caused
	some problems when linking with MOTIF widgets. Currently assume
	that Xew will not be used alone and does not need the Vendor.c
	at this point.

	The functions relating to importing of text and interpreting the
	control sequences changed into re-entrant code (old code didn't
	allow intermixed loading of multiple text streams). Affected
	ccfilter, Text, TextEd and TextImport modules. A major redesign
	of the ccfilter interface.

	columnWidth resource added to the XeText widget. Needed because
	the width of widget is not always the right width to set the text.
	Effective only, if set to NON-ZERO.

	Handling of HT (Horizontal Tab code) modified. Now it will work
	even if inserted into middle of flowing text. HT does not turn
	off line wrapping for that line any more.

	ccfilter.c/ccf_reset didn't initialize MultipleByte processing.

	Added XtNnotifyCallback resource to the XeBasic widget. The default
	translation is
		<Btn1Down>,<Btn1Up>:	notify()
	Text.c, Raster.c and Audio.c changed to support NotifyCallback. In
	Audio the toggle events changed from button Up to Down events.

	Added magic ".snd" to return XeContentFormat_AUDIO in Support.c
	function XeFindContentFormat.

	Text Widget now implements contentLength and contentOffset
	resources. Implementation decision: the length is counted
	from the given offset forward.

	Editable text widget class XeTextEd (TextEd.c) is a subclass of
	standard XeText widget. See a separate temporary documentation
	about the supported features (TextEd.doc).

	In Text.c, when calling the TextImport, the context block address
	was never saved and given to XeTextEndContent (widget address was
	incorrectly given instead).

	In RasterLayout.c, the support for FullColor on TrueColor visual
	incorrectly tested bits_per_sample, instead of bits_per_component.

Version 1.4	6 May 1993
	Audio widget changed extensively, still only support is for the
	SUN /dev/audio. It directly controls /dev/audio and there should
	not be any blocking of X Event loops. Two button events recognized

		Btn1up	TogglePlay	FREEZE <-> FORWARD, and if audio
					has layed the content, will cause
					 restart from FORWARD (instead of
					toggling it into FREEZE)
		Btn3up	RestartPlay	Forced restart, will flush output.

	RasterJPEG.c will now take input also from contentString and
	contentStream resources (only contentFile worked before this).
	TIFF content still has to become from a file.

	In TextLayout.c fixed bug in superscript computing. (Never
	do '-x/y' when x is unsigned. Instead use '-(x/y)' ...blah!).
	Ascent/Descent related things changed from 'Dimension' to 'short'
	(this fixed some buggy linespacing computations).

	The expose method in Text.c improved. Now it uses region and
	XSetRegion, and only draws text that has a chance to intersect
	exposed area. [ Introduced also a bug: inversed text sometimes
	disappears due to double drawing with XOR; cannot yet see how
	this can happen, waiting for inspiration... ]

	Fixed some complains produced by DEC CC compiler on DEC/OSF1.

Version 1.3	17 Apr 1993
	Added a new resource to XeRaster that controls the color quantification
	of 24 bit images: XeRaster.color_quantize. Four symbolic values defined
		"fast"	XeColorQuantize_FAST	F-S dithering (default)
		"best"	XeColorQuantize_BEST	ppmquant (may not work)
		"slow"	XeColorQuantize_SLOW	~ Heckbert's median cut
		"jpeg"	XeColorQuantize_JPEG	JPEG internal CQ for JPEG's
	(Note: the "jpeg" is effective only at import phase).

	More visuals supported.

	Expose method improved in Raster.c. Now only exposed rectangle of
	the image is sent to the X server. Also, RasterLayout now called
	only when needed (and not after every set_values; change was needed
	to get porthole-panner work reasonably).

	Fixed GrayScale bug in RasterJPEG.c. (Core dump from put_color_map).
	Implicit color quatification removed, JPEG color images are now
	brought to the main body as full color images.

	Adding units handling into Basic.c. (not activated yet)

	Added error handling initializations of e_methods in RasterJPEG.c
	which were missing (pointed out by Tom Lane).

Version 1.2	1 Apr 1993
	Private Colormap handling is now done either with XInstallColormap/
	XUninstallColormap or with XtSetWMColormapWindows. The default is
	to use the latter method. If the Window Manager does not honour
	the WM_COLORMAP_WINDOWS property, widget can be instructed to use
	colormap install/uninstall functions directly by setting the
	resource colormapInstall to True (this is False by default).

	When Audio content was specified with contentString resource, the
	widget only played a short section of it. Fixed now.

	XtNVisual resource has been added to XeRaster widget. Now
	individual images can use different than default visual. The visual
	resource can be set only before the widget is realized. The default
	value is inherited from the shell widget.

	A new attempt for TrueColor support into RasterLayout. It is
	slow and not complete, but if the idea works, it will be
	improved. (only tested with SunIPX 8bit TrueColor visual)

	Xew now compiles also with K&R C compiler (non-ANSI).

	X11R4 support better now (the attempt in v1.1 was buggy)

	XeDataFlow to file has been changed to use non-blocking I/O,
	improves usability of Audio widget somewhat...

Version 1.1	16 Jan 1993
	Implementation of Audio widget using Sun /dev/audio directly.
	This is mainly for testing the idea of attaching input/output
	streams to a widget using XtAppAddInput.

	Swiched to use jpegsrc.v4

	Some simple #if's added to make it easier to compile this
	package under X11R4 (this is still incomplete).

	Fixed occasional one pixel overwrites in scaling functions
	in RasterLayout.

	Fixed division by zero in XeBasicScaling, if width/height=0

	In RasterJPEG, do not feed MaxColours resource to JPEG
	quantizer. Just always quantize into 256. (Deal with
	true color later).

	RasterLayout for TrueColor worked only for 24 bit pixels,
	fixed it to work for 32 also.

VERSION 1.0	15 Dec 1992
	Changed the order of content checking into String-Stream-File,
	as specified in the documentation. Was reverse in Text widget.

	The initial state defined by graphicRendition resource is
	taken to be the	default state requested by SGR 0.

	First crack at adding implementation of SGR 30-37,39, 40-47,49
	(text foreground and background colors).

	Destroy methods for Text and Raster Widgets added.

	Fixed ISO 6937 supplementary set handling (which didn't work
	at all when the non-spacing accents were used), some conversions
	were also broken.

	Added support for the Swedish/Finnish ISO 646 national variants
	as an example.

VERSION 0.12	30 Nov 1992
