* pango-view: Allow showing glyph ink rectsligature-caret-rtl-fixesMatthias Clasen2021-08-271-11/+69

* 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.

| | | | | | | | | | | | This is just used in tests for now. If we decide to make an external log attr api, we can make this public.
| * break: Fix up word fixupsMatthias Clasen2021-08-262-14/+21
| | | | | | | | | | | | | | We were not correctly handling overlapping segments in all cases, with <span segment='word'>. Improve this. Update affected tests.
| * break: Fix sentence boundary corner casesMatthias Clasen2021-08-261-2/+2
| | | | | | | | | | | | We were not correctly handling the case where wipe out a sentence boundary after the fact, and were leaving behind a stray sentence end.

|/ | | | | | | | We were not putting a line break at the end of the text, in cases where a paragraph ends with a newline. Enforce this in all break apis. Update affected tests.

| * hyphen: Try harder to insert needed hyphensMatthias Clasen2021-08-251-4/+43
|/ | | | | | | We were forgetting to reshape runs in some situations, leading to them not having hyphens appended. This was happening when runs fit fully onto the end of a line that is wrapped anyway.

| * break: Add pango_attr_break apiMatthias Clasen2021-08-233-9/+62
| | | | | | | | | | | | | | | | | | | | | | | | So far, we've been applying attribute-based customization while doing per-item tailoring. But this is suboptimal, since it means we don't have a full view of the log attrs, and can't do invariant fixes that cross item boundaries. Therefore, add a separate pango_attr_break api that applies attributes to to the whole paragraph, and make PangoLayout use it.
