But doing it the other way round is much harder, maybe impossible. If TextCache were gone, I could simply move the ParagraphList from InsetText and Buffer::Impl to LyXText and rename 'LyXText' to 'NewParagraphList'. Then we could replace the LyXText in the NewParagraphList with a map<BufferView*, LyXText> and have almost everything in place for multiple BufferViews. (Incidentliy, this would mean, that ParIterator would again contain references to 'NewParagraphLists' - but now the Right Ones) As it stand right now we cannot do that as there is no 1:1 matching from the buffer's ParagraphList to a certain LyXText, so I can't do that first step. And I fail to see alternatives. > But you need to cache y-positions anyway. Per paragraph perhaps. This is a factor of 5 or so in a typical text document.
