Folks -

Herewith a number of bug fixes and enhancements now out on the servers.

Enjoy

-----------------------
4553PolyFixes-ar -- Andreas Raab -- 26 November 2001
Fixes two problems (reported by Kim) when using border styles with polygons:
	* gribblies when changing the border width
	* division by zero for certain border widths

4554JPEG2Fixes-ar -- Andreas Raab -- 27 November 2001
Fixes a problem with JPEG2Plugin - if not present you get #primitiveFailures rather \
than using the default plugin. Also optimizes various bits of code, removing \
(unneeded) argument tests against the receiver (which would have pointlessly \
                prevented renaming JPEGReadWriter2 into something else).
WARNING: The changes (in particular the first fix) require a new plugin to be build."

4555noAudioDir-mir -- Michael Rueger -- 27 November 2001
The 'audio' dir for ChatNotes is now only created if really needed."

4556avoidThumbnailing-sw -- Scott Wallace -- 27 November 2001
Fixes a bug in the mechanism provided for avoiding thumbnailing of certain morphs for \
parts-bin purposes."

4557haloMenu-sw -- Scott Wallace -- 27 November 2001
An attempt at rationalization of the now hopelessly-unwieldy red-halo menu for \
                morphs.  
* the clustering together of most (all?) of the standard checkbox-bearing items
* the factoring of groups of items into separate methods which return coherent \
                submenus.
* menu items mirroring halo actions are provided generically; this allowed deletion \
of a number of custom methods that had served only to offer halo-action \
                functionality.
* full access to all the new border styles is now available via menu.
* a new checkbox item governing whether an object should resist removal is added.  \
                When set, user confirmation is required before a dismiss-via-halo is \
                carried out.
* a few minor rewordings tried out (those in love with 'sticky' might scream.)
* a slight regrouping of the world menu, and a fresh factoring of the world's halo \
                menu.
* balloon-help provided for all top-level items in standard world menu.
* the old #addAddHand... protocol is left behind (though retained for backward \
compatibility with client code) -- it was *never* used for its announced purpose, and \
thus only added confusion.  All morph-specific additions are now channeled through \
                #addCustomMenuItems...
* if the new #selectiveHalos preference is true, then inappropriate halo handles are \
no longer offered in a halo.  Thus, for example, if a morph is marked as being \
                resistant to removal, it will not offer pink (dismiss) handle.
NOTE: to regain the former comfort of the old regime, set the selectiveHalos \
preference back to false.  This update sets it to true so you can immediately feel \
the difference." Preferences addPreference: #selectiveHalos categories: #( Halos) \
default: true balloonHelp: 'When this is set to true, halo handles that are deemed \
inappropriate are not shown.  Thus, for example, if a morph is marked as resistant to \
removal, it will not offer a pink ''dismiss''.'.

4558FixPolygonScale-di -- Dan Ingalls -- 28 November 2001
Polygons and related shapes (Curves, Stars) do not need a flex shell to change their \
size and rotate.  However, the Player logic that controls scaling and rotation \
expects a flex shell to be used. This caused walkbacks in the past, and has been \
worked around recently by no-oping these operations. This changeSet causes a flex \
shell to be used when players are involved, but continues the non-flexed control from \
the halos, owing to its better visual results and consistency with constant border \
widths when resizing, eg, ellipses and rectangles from the halo.

4559MinesTweaks-di -- Dan Ingalls -- 26 November 2001
Two changes specific to Mines, and one generic to Morphic that greatly speed up \
creation of the board.

4560noSelectiveHalos-sw -- Scott Wallace -- 29 November 2001
Resets the experimental selectiveHalos preference to false.
Relaxes the check for whether a resize handle is wanted."

4561haloCatOops-sw -- Scott Wallace -- 29 November 2001
Fixes a capitalization error in the category of a recently added preference.  You'll \
need to get a fresh Preferences Panel to feel the difference.  Change set consists of \
this preamble only" Preferences setCategoryList: #(halos) forPreferenceNamed: \
#selectiveHalos

4562GenieUpdateToV202 -- Nathanael Scharli and Stephan Rudlof -- 15 August 2001
***  Genie v2.02 (Update from Genie 1.0)  ***
This changeset updates Genie to version 2.02. The new features are:
- More than 10 times faster lookup (with VM plugin)
	- New VM plugin (by Stephan Rudlof) and optimized image level code
	- Execute 'CRRecognizer checkPluginVersion' and watch the Transcript output in order
	to check availability/compatibility of the VM plugin.
- Faster graphical feedback (especially imporant for PDAs)
- New dictionary format
	- Old dictionaries are automatically converted to the new format. This convertion \
includes  modification of the parameters 'speed' and 'curvature relevance'. This is \
necessary to retain  the behavior of the dictionaries with the optimized algorithms.
	- The new format is backwards compatible. This means that new dictionaries can still \
be used  with Genie v1.0. However, the parameters 'speed' and 'curveture relevance' \
are interpreted  slightly different, which may lead to slower recognition or \
                inaccuracies in Genie v1.0.
- Improved UI (Improved morphs to inspect/modify gesture dictionaries resp. display \
                properties)
- BugFixes
IMPORTANT information about the Genie VM plugin
The Genie VM plugin makes Genie about 10 to 20 times faster. Especially on slower \
machines (PDA, etc.), it is really worth using it and it makes Genie much more fun!! \
Testing the plugin To see whether the plugin is available and compatible to the image \
level code execute 'CRRecognizer checkPluginVersion' and watch the Transcript output. \
To compare the performance of the primitive to the original performance do the \
following: 1) Load the gesture dictionary \
'http://www.iam.unibe.ch/~schaerli/genie2/GenieTest.ggd' in your image. 2) Execute \
'CRStrokeFeature testPrimitivePerformance' and watch the transcript output. 3) \
Execute 'CRStrokeFeature testOriginalPerformance' and watch the transcript output. 4) \
Compare the output of steps 2) and 3). The primitive should be about 50 times faster. \
If you are not sure whether the primitive works correctly, do the following: 1) Load \
the gesture dictionary 'http://www.iam.unibe.ch/~schaerli/genie2/GenieTest.ggd' in \
your image. 2) Execute 'CRStrokeFeature testPrimitive' and watch the transcript \
output. Compiling and installing the plugin
The Genie plugin may already be part of your VM (execute 'CRRecognizer \
checkPluginVersion' to check). If not, you can compile and install it yourself, by \
doing the following: 1) Generate the C-file by executing 'GeniePlugin translate'. \
This writes the file 'GeniePlugin.c' into the subdiretory 'GeniePlugin'.  2) Compile \
the plugin and make the resulting dynamic library available for the VM. (This step is \
platform dependent. On Windows, you have to get the VM sources, build the plugin \
(enter 'build GeniePlugin.dll') and copy the resulting file GeniePlugin.dll into the \
                Squeak VM folder).

AGenieIntroduction."

4563DirectionHandles-ar -- Andreas Raab -- 29 November 2001
Makes the direction handles option a per-morph on/off preference. Only stores its \
value if the morph goes against the system wide pref."

4564arrowDeltaEtc-sw -- Scott Wallace -- 29 November 2001
Allows the deltas applied via little green arrows on numeric readout tiles to be \
specified (formerly, the delta had always been one) -- and uses this to make the \
stepsize of the arrows for #scaleFactor be .1.  Also makes the default float \
precision of #scaleFactor be such that one decimal place is always shown."

4565FixPolygonHeading-di -- Dan Ingalls -- 29 November 2001
Further to the changes of 'FixPolygonScale', this changeSet (by removing a method ;-) \
causes heading to be reported correctly for both flexed and unflexed polygons.

4566TextSuccessorFix-di -- Dan Ingalls -- 29 November 2001
Kim Rose reported a while ago that there was a walkback when trying to turn a GeeMail \
from 1-column book to a 2-column book and Leo Burd recently noted the same problem.  \
Bob Arning reported a related problem with simple TextMorphs:  In a new TextMorph \
choose 'add successor' from its menu  Try to add text to first TM, get 'Error: \
Inconsistency in text editor' This change fixes the simple manifestation of this \
problem, and hopefully the GeeMail problem as well, though I have not tested it.
