Problem Description

Reverse of Offscreen Rendering, I want to import a external texture into web rendering systems (WebGPU, WebGL) without CPU - GPU copying.

Proposed Solution

Find a way to import a external texture handle into a web texture container. Avoid patches.

I'll try implement this myself.

media::VideoFrame seems promising, as it is also used in OSR. It is wrapped by blink::VideoFrame and blink::V8VideoFrame

Let's track at the draft PR.
