* Use a better size for missing spaceMatthias Clasen2021-12-211-39/+4
| | | | | | | | | | Follow the Microsoft Typography recommendations from https://docs.microsoft.com/en-us/typography/develop/character-design-standards/whitespace and use half of an em for missing space. Update affected tests. Fixes: #647
* fc: Implement get_absolute_sizeMatthias Clasen2021-12-211-0/+14
| | | | No surprises here.
* Add a private api to get the font sizeMatthias Clasen2021-12-212-1/+21
| | | | | | | | Add a private vfunc to get the (absolute) size of a font. This default implementation just pulls it out of the font description, but we can do implement this cheaper without copying the font description.
* CosmeticsMatthias Clasen2021-12-191-9/+10
| | | | | Rename some variables, so we actually know what these matrices are.
* Fix line height with emulated small capsfix-small-caps-line-heightMatthias Clasen2021-12-194-14/+40
| | | | | | | | When we change font scale for emulating small caps, keep the original font around in the analysis, and use it for calculating the run height. Fixes: #622
* Add some private apiMatthias Clasen2021-12-192-0/+63
| | | | | | Add some api to let us store another font in a PangoAnalysis. This will be used in the following commits.
* Improve line width accountingMatthias Clasen2021-12-181-1/+1
| | | | | | | We want to avoid trading chars for hyphens in the margin beyond the set width. Fixes: #646
* layout: Fix a cornercase of line width accountingMatthias Clasen2021-12-181-8/+12
| | | | | We don't collapse space at the very end, so we should count such spaces towards the line width.
* serializer: Fix a typoMatthias Clasen2021-12-181-1/+1
| | | | | | Oops, we were not serializing the height at all. Update all affected tests.
* Add some docsMatthias Clasen2021-12-181-0/+25
| | | | Add doc comments for some private API.
* fc: CleanupMatthias Clasen2021-12-183-3/+3
| | | | | | Stop using fcfont->matrix. This is just a redundant copy of the matrix that is already available in the font key. Just use that.
* cairo: Work harder to measure spacemore-space-tweaksMatthias Clasen2021-12-171-3/+21
| | | | | | | | | | | When coming up with a width for a missing space, we were just measuring the hex digits. But in subsetted fonts, such as the ones we use for ci, hex digits might well be missing. Take that into account and still provide some nonzero width for space. Update affected tests.
* shape: More tweaks to space handlingMatthias Clasen2021-12-171-4/+16
| | | | | | | | | | | | | | It is a difficult dance between HarfBuzz and pango which glyphs we let hb synthesize, and which ones we need to fake ourselves. HarfBuzz knows how to create other spaces from 0x20, so if the font is lacking spaces, we want to tell HarfBuzz that we don't have that glyph *except* for 0x20 where we need to fake one, and provide HarfBuzz with a suitable width. Update affected tests.
* Revert "Fix advance widths with transforms"fix-vertical-regressionMatthias Clasen2021-12-171-16/+29
| | | | | | | | | This reverts commit ccb651dd2a876a4f4a4cb9351f05332173e709ba. This broke vertical text rendering, see https://gitlab.com/inkscape/inkscape/-/issues/2950. Update affected tests and add a vertical test.

| * Fix Arabic format charsMatthias Clasen2021-12-161-18/+22
