vkvg VS bazel-skia

Hi, I don't know where to ask this, so, since we're talking about Pango, a GNOME project, I ask it here. There's this library called [`vkvg`](https://github.com/jpbruyere/vkvg) which follows the Cairo API and uses Vulkan as backend, and I thought it would be a good idea to port `pangocairo` to "`pangovkvg`". I created a repository [here](https://github.com/Rubo3/pangovkvg) and I'm focusing on porting it to Linux, so I removed the CoreText and Win32 code. [Here](https://github.com/jpbruyere/vkvg/issues/66) is the issue used to coordinate between `vkvg` and `pangovkvg`. Is there anybody interested and willing to help?

I'd like to develop native Wayland programs, and I don't really want to use toolkits like Qt or GTK, I need something just above OpenGL or Vulkan which only draws to a surface, I handle the rest. cairo + pango are a very nice pair, but cairo is mostly dead, the only way to make it Wayland native is through its OpenGL context, which unfortunately is still experimental even after many years. I found about VKVG, which wants to be Cairo based upon Vulkan, but that's "in early development stage". Generally I find dead drawing libraries, full toolkits or game engines which I don't want, or low level libraries. It seems to me that Linux doesn't have a solid middle-level graphics library anymore, or am I missing something? Do you know some libraries to recommend?

I tried cairo + pango as they are a nice pair, but cairo's OpenGL support is only experimental. So I found about VKVG, but that's "in early development stage". I don't want to use a full toolkit, just a stable library which abstracts raw graphics APIs, as the ones I've mentioned. Which ones do you recommend?
