Module readback 

GPU readback utilities.

Provides facilities for reading GPU framebuffer / texture data back to CPU-accessible memory. On the CPU-stub backend this is a direct copy (identity transform); on a real GPU backend the same interface wraps wgpu::Buffer::map_read.

Example

use oximedia_gpu::readback::GpuReadback;

let data = vec![0xFFu8; 4 * 4 * 4]; // 4×4 RGBA
let out = GpuReadback::download(4, 4, &data);
assert_eq!(out, data);
