I have some text items whose glyphs cannot be determined until layout. The text string might contain a marker to draw the current page number, or to sequentially number paragraphs, etc. The glyphs can be determined only by the layout manager; different layout managers for the same text storage might display different page numbers, for example.

One alternative to the glyph generator is to subclass NSTextAttachment. The attachment cell can query the text container / layout manager for any information it needs during cell frame calculation and drawing.
