Use a simple chooser tool instead of menus for lists that are very long. Makes it easier to find things since scrolling is required anyway.

MultiCompositionScanner needs to implement #computeDefaultLineHeight. MultiDisplayScanner now vectors the actual font display through its bitBlt instance which then dispatches into the font giving an extra level of indirection which is useful if the display machinery isn't actually being used with a form-based backend.

A little white lie: When loading sizable packages, most of the time can be spent in notifying the observers. Tell the users that we're still installing because it's embarrassing to let them know that we're wasting our time in notifications.

Just for fun, optimize a bit more WideCharacterSet bitmap:do:
1) it now enumerates Characters in ascending value
2) the trick to eliminate the lowest bit is just beautiful (a generalization of isPowerOfTwo)
Of course, I could also tabulate all the bits in an Array of 255 ByteArray, but that would be no fun...

Oops, sorry for double posting, I forgot to update the comment.
Note that it would be interesting to see how non inlined version performs in COG:
| byte byteOffset |
1 to: aMap size do: [:i |
        (byte := aMap at: i) = 0 ifFalse: [
                byteOffset := (i bitShift: 3) - 9.
                [aBlock value: (byteOffset + byte lowBit).
                (byte := byte bitAnd: byte - 1) = 0] whileFalse]]

Implement subclassResponsibility remove:ifAbsent: in CharacterSet family.
Cache the byteArrayMap of a WideCharacterSet.
Update class comment.
