Enum SurfaceSource 

pub enum SurfaceSource {
    Texture(AppTexture),
}

Source of pixels for a crate::tree::Kind::Surface widget.

Today only Self::Texture is shipped. A Callback(...) variant is planned as a future, more efficient path that hands the backend encoder to the app during paint; the Source enum exists from day one so that addition is non-breaking for callers.

Variants

Texture(AppTexture)

App-owned, app-filled GPU texture. Sampled by the backend during the existing paint pass — no shared encoder, no extra render pass.
