Render small-caps font variant #1611

wants to merge 7 commits into from

Commits on Jun 24, 2020

  1. render small-caps font variant 

    - pango has a PANGO_VARIANT_SMALL_CAPS variant that can be added to the font description, but setting it doesn't cause text to be rendered in small-caps, even if the font supports it
- adding the appropriate opentype features to the layout's attributes list will use the font's small-caps glyphs if it provides them

  1. added textAttributes field to state struct 

    - the font-variant state will get out of sync with the fontDescription across context-saves & restores unless we keep a copy of the PangoAttrList around

  1. only set opentype features on sufficiently new versions of pango 

    - the pango NEWS file suggests 1.37.1 was where the `pango_attr_font_features_new` call was added...

  2. skip the small-caps variant test on windows 

    - it can be enabled if/when the pango version is updated
