* test-layout: Add a --show-fonts optionbaseline-shiftMatthias Clasen2021-08-311-0/+15
| | | | A bit more natural than the environment variable.
* test-layout: Disable fragile checksMatthias Clasen2021-08-311-175/+0
| | | | | | | I added these for improved coverage, but they get in the way, Should probably just move these kind of checks to another place and leave this test focused on dumps.
* Add horizontal displacementMatthias Clasen2021-08-315-39/+78
| | | | | | | | | | | Apply horizontal displacements for superscripts and subscripts that are provided in font metrics. This noticably improves the placement of superscripts in italics. Currently, we only apply these displacements in post-processing, and ignore the width changes during line-breaking. This could be improved by moving the baseline handling into the line-breaking proper.
* markup: Change <sup> and <sub>Matthias Clasen2021-08-312-22/+8
| | | | | | | | Use the new baseline-shift and font-scale attributes to reimplement <sup> and <sub>. Now they take font metrics into account and nest properly.
* Implement font-dependent scalingMatthias Clasen2021-08-316-21/+217
| | | | | | | Add a new font-scale attribute to indicate font size changes due to super- and subscript shifts, and handle it during item post-processing to find the right font sizes.
* Implement baseline shiftsMatthias Clasen2021-08-318-45/+231
| | | | | | | | | | | Add a new baseline-shift attribute, which is similar to rise, but accumulates. In addition, it supports font- relative values such as superscript and subscript. We implement support for this by computing baseline shifts for run during line post-processing, and storing them in the runs. The renderer now takes these shifts into account when rendering layout lines.
* Make ellipsize code saferMatthias Clasen2021-08-311-2/+1
| | | | | | We are going to add new fields to PangoGlyphItem, so zero-initialize the one we are allocating here in ellipsize.c.
* Merge branch 'coretext-font-describe' into 'main'Matthias Clasen2021-08-313-14/+17

| * tests: Test font roundtrips on MacOscoretext-font-describeMatthias Clasen2021-08-311-12/+5
| | | | | | | | | | | | We were skipping the test that would have found the brokenness in the previous fix. Lets see if we can get the test working on MacOs.
| * coretext: Set size on font descriptionsMatthias Clasen2021-08-312-2/+12
|/ | | | | | | | Set a size on the font description returned by pango_font_describe(). Otherwise, scaling it doesn't work. Fixes: #610

|/ | | | | | These are not very reliable for things other than marks, but even that is useful for debugging cluster handling.

| | | | | | | | If we don't have them, just do the fallback.
| * Add pango_glyph_string_index_to_x_fullMatthias Clasen2021-08-292-24/+72
| | | | | | | | | | | | This variant of pango_glyph_string_index_to_x takes log attrs so it does not have to compute them when it needs them to determine grapheme boundaries.
| * Try harder to disect clustersMatthias Clasen2021-08-291-15/+34
|/ | | | | | | | | | We need to take into account whether the characters we are counting are actually cursor positions, else we are bound to look for more carets than the font has available, sometimes. This change would benefit from passing log attrs into pango_glyph_string_index_to_x.
