Hi Sean, you can take a look at Athens-PangoCairo (in squeaksource). Using NativeBoost, i'm using the Pango layout library [1], and the Pango-Cairo binding [2], to avoid laying out text using the outdated (and messy) stuff in the image.
Check out the classes: ParagraphDescription & AthensPangoCairoParagraph. I'm using them as the basis for the TextShape,LabelShape, and EditableTextShape in Shapes / Gaucho ( using TextEditor, SingleLineEditor ). Maybe somebody can do the same for Morphic? use Pango to layout the text, and code a new TextMorph on top of it?
