This commit fixes a subtle problem when trunating text widgets that contain multiple newline-delimited paragraphs. Paragraphs are the unit of text shaping, so we divide the text into paragraphs and then iterate those paragraphs performing shaping and line wrapping. If we have a maximum number of lines to fill, we stop iterating paragraphs when we use all of the available lines. Usually, if we fill all of the lines the text shaper will insert the truncator symbol. However, if we exactly fill all of the lines with the end of a paragraph, the line wrapper is able to fill the line quota without actually truncating any of the text in that paragraph. Thus it doesn't insert a truncator even though subsequent paragraphs were truncated (it has no way to know). To fix this, I've taught the line wrapper about an explicit scenario in which we always want to show the truncator symbol *if* we hit the line limit, even if all of the text in the current paragraph fit. I've then plumbed support for that through our text stack. Signed-off-by: Chris Waldon <christopher.waldon.dev@gmail.com>
