notes regarding possibly making graphics apis (wgpu?) have
interoperable buffers with tensor libraries
note: i think i already implemented this some years ago, probably for
raw opengl or vulkan. dunno where that is
- i don't immediately see a way in wgpu to get a raw pointer
- i heard opengl has a raw pointer function
- i think wgpu uses opengl ES and vulkan

- because gles, vulkan, metal, direct3d, and anything else, have
handles to their buffers, it's intuitive that they must be
interoperable -- the handles would be passed.
any underlying transformation of the handles to support interprocess
use would be documented in the interprocess importer for the backend.

It also would let people write pseudo-shaders in many other language and libraries.
