Twenty new updates are now available on the external 3.3a update 
servers.  These are mostly bug-fixes.

4962BBFixAlphaRule -- Andreas Raab -- 21 August 2002
Adds a #fixAlpha:with: combination rule to BitBlt.

4963searchTweaks-sw -- Scott Wallace -- 22 August 2002
Various tweaks and enhancements to the search-in-viewer facility, including...
* Makes the search-in-viewer work when the search button is pressed 
as well when enter or return is used to submit the search.
* When a user submits a search request in a Viewer and no hits are 
found, explicitly inform the user about this.
* Adds to the menu for every phrase in a viewer the item 'show 
categories...', which will present you with a list of all the viewer 
categories in which the item will be found; if you choose any of 
these, a viewer pane specifically for that category will replace the 
searching-viewer pane

4964debuggerButtons-sw -- Scott Wallace -- 22 August 2002
Makes the conventional code-tool buttons (senders, implementors, 
versions, inst vars, etc.) available in a debugger, if the 
#optionalButtons preference is true.  This is independent of the 
debugger-specific button pane (Proceed, Restart, Send, etc.), which 
is always shown and was never governed by the optionalButtons 
preference anyway.
This change does not affect mvc debuggers.

4965moreViewerTweaks-sw -- Scott Wallace -- 23 August 2002
Further tweaks to search-panes-in-viewer:
* Make the wording of the help-message for the search button be 
couched in terms of tiles, not selectors.
* Add new search panes, when they are requested, at the top of the 
viewer rather than at the bottom.

4966fromAppleHill-sw -- Scott Wallace -- 4 September 2002
Three issues that arose in the company of Kim and BJ at Apple Hill:
(1)  Newly drawn sketches sometimes did not show up in the playerlist 
of the Presenter (because its playerList cache was not getting 
invalidated;) thus their names would not show up in the script-name 
popup, and also sometimes they would not get stepped.  This is a bug 
that actually goes back more than four years.
(2)  Launching a PDAMorph in a system that lacked a .sources file, 
(such as a typical PlugIn image), would raise an error, because 
PDA.initialize assumed that class comments would always respond to 
the selector #string, which Texts do but which (perhaps surprisingly) 
Strings themselves do not.
(3)  For the Squeakland image, make four custom preference adjustments.
This update is intended to apply both to 3.3a and the Squeakland 
plug-in update streams; the preference changes will only be felt in 
Squeakland

4967B3DRendererFlags -- Andreas Raab -- 5 September 2002
Adds renderer creation flags for creating HWA renderers. Besides 
using software/hardware renderers (which are now handled through the 
flags and no longer through individual booleans) a new flag is 
introduced to indicate the request for stencil buffering."
B3DHardwareEngine addClassVarName:'B3DHardwareRenderer'.
B3DHardwareEngine addClassVarName:'B3DSoftwareRenderer'.
B3DHardwareEngine addClassVarName:'B3DStencilBuffer'.

4968FixBalloonModule -- Andreas Raab -- 5 September 2002
(Incompletely) fix the location of BalloonEngineConstants. Somehow it 
got moved from Balloon.Engine to Balloon.Drawing although there is no 
trace in the updates I can see. The CS at least allows generation of 
new VMs but it is incomplete since there are various other references 
that are NOT fixed.

4969divers-sw -- Scott Wallace -- 4 September 2002
* Fixes the bug that would drop you into a debugger when you used the 
'find window' feature when there was a window with a zero-length 
title.
* Only show the extra row of buttons in the debugger (as per update 
4964) if the preference #extraDebuggerButtons  is true. To minimize 
upset.
* When a message-list shows a class definition or hierarchy, now 
shows something appropriate in the annotation pane.
* Repairs the long-standing annoyance that methods imported via 
change-list browsers and versions browsers did not get noted in the 
recent-submissions list. and hence would not be seen in 
recent-submissions browsers.
* Fixes a bug that could make a pop-out behavior change for flap tabs 
not work properly.
* Fixes the bug that String.withFirsCharacterDownshifted would 
generate an error when called with an empty string.

4970overlaps-sw -- Scott Wallace, Leo Burd, John Maloney -- 6 September 2002
Adds an 'overlaps' test to the etoy vocabulary.  This is simple 
object-to-object collision detection, and is smart about jagged 
edges, transparency, etc.
NOTE:  The 'touchesA:' test is changed to exploit this better 
collision detection (previously it had only looked for bounding-box 
intersection) but is otherwise left with its quite inscrutable 
semantics (consult comment in Player>>touchesA: for details.)
Also, this update changes the behavior of the 'show categories' 
function from the viewer-entry menu; now, instead of replacing an 
existing viewer pane with one pointing at the new category, it *adds* 
a new viewer pane showing the new category -- per Kim's suggestion

4971fasterListOfMany-dvf -- Daniel Vainsencher -- 7 July 2001 (originally ;-))
This update prevents significant slowdown for Squeak when looking at 
really long lists that use this morph (happened to me using the 
""recently logged changes"" feature on a changes file with lots of 
updates)
drawOn: for this class was O(N*N) in the number of list items, now O(N).
sw 8/30/2002: merged Daniel's speedup with two other changes to this 
method that have appeared in the update stream in the meantime"

4972fixWorldGradient-ar -- Andreas Raab -- 7 September 2002
Fixes the problem when trying to set the world's gradient color

4973xmlFix-mlr -- Michael Rueger -- 9 September 2002
Convert to uppercase before parsing numbers, in order properly to 
support bases > 10.
Replace 16-bit characters with spaces.

4974knownRenames-mlr

4975More3DPrims-ar -- Andreas Raab -- 18 September 2002
Make four more matrix operations run in primitives for speed and less 
pressure on GC.

4976B3DPrimFix -- Andreas Raab -- 27 September 2002
Fixes a bad mistake in one of the new primitives.

4977fixesEtc-sw -- Scott Wallace -- 3 October 2002
* Fixes 'one last' bug in the revamped implementation of #spawn: if 
the spawning browser were looking at the #all category, the spawned 
browser was being given a faulty message-category-list index, which 
would result in difficulty submitting the method later on.
* Fixes the annotation for class-comment for the case when the 
selection is a metaclass method.
* Fixes Wonderland.makePlaneNamed so that it returns the resulting actor.
* Fixes Scamper.back so that it does not generate an error when the 
document index is out of range.
* Bulletproofs MenuItemMorph.mouseEnter against an orphaned condition 
that is known to occur.
* Fixes bug that had made text on menu tiles editable; click on menu 
tile again brings up the list of alternatives.  I don't know just 
when or why this got broken, but it was reported recently by Alex 
Peake.
* Fixes MenuItemMorph.veryDeepFixupWith: so that it does not bomb 
when #arguments is nil.
* Adds a menu item for Recent Submissions browsers that allows the 
currently-selected method to be removed from the RecentSubmissions 
list.  This is useful to rid the Recent Submissions browser of 
methods that were temporarily changed for debugging and subsequently 
reverted.
* FileList2 will now return a read-only stream on a file if the 
default read/write-access cannot be obtained.  Practically, speaking, 
all known uses of FileList actually only need read-only access anyway.

4978lengthEtc-sw -- Scott Wallace -- 3 October 2002
* In viewers, replaces the former 'height' and 'width' variables with 
'length' and a redefined 'width'.
* Length is measured in the direction the object is heading,  Width 
is the orthogonal measure.  These two measures are now invariant as 
an object rotates (except for small round-off artifacts.)
* Adds (this is a temporary name, until Alan tells me what the real 
name is ;-) #headingTheta, which gives the angle from positive-x that 
an object's major axis (i.e. the direction in which the 'length' is 
computed) makes.
* Puts commands for switching into and out of 'vector mode' into the 
personal menu for Alan (i.e. only if the hard-coded #isFlagship 
preference is true.)
* Note that the length and width computations for PolygonMorphs are 
very tortured and special-cased and slow.  I would welcome this being 
cleaned up.  AFAIK it is only PolygonMorph that is problematical in 
this way.
* For the particular forcing function behind this work, namely Alan's 
'players-as-vectors' etoy work, PolygonMorphs that have precisely two 
vertices are special-cased to have intuitively correctly behavior for 
length and width; the Arrow found in the Objects catalog is a good 
prototype to use.
* Fixes a long-standing bug in 
methodInterfacesInPresentationOrderFrom:forCategory:

4979decimalPlaces-sw -- Scott Wallace -- 3 October 2002
* When the user text-edits the value in an UpdatingStringMorph that 
holds a numeric value (e.g. in a Viewer or Watcher,) the user's 
type-in is now parsed to determine how many decimal places to show in 
that readout from then on.  Thanks to Kim Rose for this suggestion.
* When an UpdatingStringMorph has a particular number of 
decimal-places specified, that number of decimal places is now always 
actually shown.  Formerly integers were shown without decimal points 
completely, whatever the number of decimal places specified, and 
trailing zeros were generally not shown.  Now, if you have asked for 
two decimal places, the readout will always show precisely two digits 
after the decimal point.
* When the user asserts a particular number of decimal places in a 
readout for an etoy built-in variable such as x or width, that 
preference is remembered and used whenever that variable is 
subsequently viewed.
* When an arrow-setter phrase is torn off from a viewer, if it 
pertains to a numeric variable for which a decimal-places preference 
has been expressed, that preference is reflected on the constant tile 
in the spawned assignment phrase.
* The #heading pseudo-slot is no longer gratuitously rounded.
* The main viewer-entry menu (activated by clicking on the menu icon 
next to a variable name in a viewer) now contains a 
set-decimal-places item for *all* numeric-valued variables, not just 
for user-defined instance variables.

4980thumbHolderFix-bf -- Bert Freudenberg -- 30 September 2002
Makes getValueAtCursor and getGraphicAtCursor for a Holder showing 
thumbnails return the represented morph. Before, the thumbnail itself 
was returned which caused the animation to be played at thumbnail 
size.

4981alphaDropTest-ar -- Andreas Raab -- 17 September 2002
Fixes a weird problem with translucent text drop shadows.
