@cImport is going to disappear in Zig 0.17. Its deprecated in Zig 0.16.
Let's remove it now.
Replace @cImport with addTranslateC across pkg/ packages. Each
package now has a c_import.h header that is translated at build
time via addTranslateC and exposed as a "cimport" module import.
Converted packages:
- dcimgui
- fontconfig
- freetype
- glslang
- harfbuzz
- macos
- oniguruma
- opengl
- sentry
- spirv-cross
- wuffs
Omitted:
- gtk4-layer-shell - This has a bit more complexity with how it
interacts with GTK headers, so I need to consider this a bit more.
- src/ - It'll be cleaner to do this separately.
FcLangSetHasLang returns FcLangResult enum values:
- FcLangEqual (0): Exact match
- FcLangDifferentTerritory (1): Same language, different territory
- FcLangDifferentLang (2): Different language
The previous comparison to FcTrue (1) caused:
- Exact matches (0) to incorrectly return false
- Partial matches (1) to incorrectly return true
This fix changes the comparison to FcLangEqual (0) so hasLang()
correctly returns true only for exact language matches.
Fixes emoji font detection which relies on checking for 'und-zsye'
language tag support.
