* renderer: Use ink rects for line lengthsunderline-kerningMatthias Clasen2021-08-271-6/+6
| | | | | | | | | When rendering underlines and the like, we should use ink extents, since the logical extents will get shortened by kerning, which can be pretty noticable when underlining individual glyphs, such as the T in To. Fixes: #139

* Try harder to find positions in clustersMatthias Clasen2021-08-271-3/+32
| | | | | | | Try to find a single non-mark glyph in a multi-glyph cluster to use its ligature caret information. This fixes situations in Arabic where you can have marks on top of ligatures, e.g. ﻉﻭ.
* Take kerning into account for ligature caretsMatthias Clasen2021-08-271-0/+3
| | | | | | | The ligature caret positions returned by hb_ot_layout_get_ligature_carets are 'unshaped' metrics. We need to take the kerning into account that is applied during shaping, and shows up in the glyphstring as x_offset.
* Fixes for rtl cursor positionsMatthias Clasen2021-08-271-1/+4
| | | | Still not working quite right, but getting closer.
* test-shape: Show cluster boundaries correctlyMatthias Clasen2021-08-271-11/+12
| | | | | | Cluster boundaries were cutting off the first character of a new cluster. Not great if the tools print out misleading information.
* test-shape: Add an option for hex charsMatthias Clasen2021-08-271-1/+20
| | | | | This is useful when trying to understand the output for scripts I don't read.
* pango-viewer: Number caretsMatthias Clasen2021-08-271-0/+7
| | | | | When showing caret positions, put a little number next to them to indicate the order.
* pango-view: Be more careful about caret positionsMatthias Clasen2021-08-271-12/+23
| | | | | Don't show carets where they don't belong. Skip non-cursor positions.

| | | | | | | | | | | | What the docs were saying is no longer strictly true, now that we are using font metrics. Update them, and add an illustration.
| * Tweak the drawingMatthias Clasen2021-08-263-59/+53
| | | | | | | | | | Since the text is talking about zero-width rectangles, show one of those, instead of a sloped caret.

| * break: Fix up word fixupsMatthias Clasen2021-08-262-14/+21
