Skewed output when changing resolution of new `headless_renderer` example about bevy HOT 4 CLOSED

The AppConfig struct is where I started, I just decreased the width by one, e.g. on line 68-72:

let config = AppConfig {
        width: 1919,
        height: 1080,
        single_image: true,
};

...which results in the 45° skewed image (second screenshot). I also tried adding 4, 8, 16, and 32 to the width to see if that worked, and it didn't- but just now I tried adding 64 (1952x1080) and it worked! So it seems that the width has to be multiples of 64. It wouldn't be a problem for most fixed resolutions but for my use case a user might resize it to anything.

If found the root of problem. That is in copying from image to buffer, because copy_texture_to_buffer can copy image only by rows aligned wgpu::COPY_BYTES_PER_ROW_ALIGNMENT. That is why image in buffer can be little bit wider. I will fix copying from buffer to resulting image.

Oh great! I tried digging but wgpu calls are a bit beyond me at the moment. Thanks for your help!
