@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.
This commit is very large, representing about a month of work with many
interdependent changes that don't separate cleanly in to atomic commits.
The main change here is unifying the renderer logic to a single generic
renderer, implemented on top of an abstraction layer over OpenGL/Metal.
I'll write a more complete summary of the changes in the description of
the PR.
