Find a better replacement for firstDestX inst. var. usage (my previous fix broke selection of first char in the line, because a MultiCharacterBlockScanner would never have set firstDestX).
I wonder if this handling is really necessary though...
Remove unused presentationText:

Correct this glitch: when a text was centered or right flush, clicking at the very left of text morph would incorrectly position the text cursor.

Don't setStopConditions twice in CharacterBlockScanner and DisplayScanner in MVC compatibility methods.
SharedPools are inherited in Squeak, so don't declare TextConstants in CompositionScanner.

Reduce some differences with the CharacterScanner hierarchies:
This will fix a regression - centered Paragraph is not displayed corectly in MVC because inst. var. alignment was used before set in the scanner.
This was solved in 2003 in http://ftp.squeak.org/updates/6188CenteredTextFix-BG.cs
But the fix was applied on CharacterScanner branch only, while MultiCharacterScanner was already forked.
Then the MultiCharacterScanner displayLines:in:clippedBy: was connected in 2005 (from the timeStamp of the method, maybe not the inclusion in official images, you'll have to dig the updateStream).
Funnily, the selection did still use a CharacterBlockScanner, so was correctly centered (outside displayed text)

Fix theFirstCharCrossedX is a bit more straight replacement of crooked itsNotTheFirstCharThatCrossedX..
And it should be taken into account in (multi) display scanner, otherwise, the display scanner does not honour the composition...
Apply the fix of Graphics branch to avoid displaying the cursor at window left in centerd alignment.

=============================================

Copy the multi-lingual methods from MultiCharacterScanner hierarchy that were missing in CharacterScanner hierarchy.
Note that this does not include the precomposed unicode Combining which deserves a rewrite.
Also note that non-space breakable chars are handled a bit differently in CompositionScanner in order to make the minimal change that could work.
Start using the CharacterScanner hierarchy instead of the Multi one.

Remove now unused MultiCharacterScanner hierarchy
Reminder: we will have to rewrite scanMultiCharactersCombiningFrom:to:in:rightX:stopConditions:kern:

Take font baseKern into account when measuring a String (a small diff with defunct Multi*).
Create a specially crafted MeasuringStopConditions and use it when measuringString.
This way, initializeStringMeasurer is no longer required and deprecated.

=============================================

Name: Graphics-nice.239
Ancestors: Graphics-nice.238

Remove some dust from CharacterBlockScanner surface (just sanitize before we operate deeper)
- don't copy lastSpaceOrTabExtent or lastCharacterExtent Points, we do not mutate them (since 2000) but create anew (see lastSpaceOrTabExtentSetX: and lastCharacterExtentSetX:)
- don't (ab)use == to compare numbers (even integer indices)

=============================================

Name: Graphics-nice.240
Ancestors: Graphics-nice.239

Remove the inst. var. lastCharacter of CharacterBlockScanner, because it is not a state.
