在Bevy游戏引擎中，将1000x1000像素的纹理分配给SpriteSheetBundle大约需要5秒

use bevy::prelude::*;

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup.system())
        .run();
}

fn setup(mut commands: Commands, mut texture_atlases: ResMut<Assets<TextureAtlas>>) {
    // 加载纹理
    let texture_handle = {
        let texture = Texture::new_fill(
            Extent3d::new(1000, 1000, 1),
            TextureDimension::D2,
            &[255, 0, 0, 255], // 红色填充
            TextureFormat::Rgba8UnormSrgb,
        );
        let texture_handle = textures.add(texture);
        texture_handle
    };

    // 创建纹理图集
    let texture_atlas = TextureAtlas::from_grid(texture_handle, Vec2::new(100.0, 100.0), 10, 10);
    let texture_atlas_handle = texture_atlases.add(texture_atlas);

    // 创建SpriteSheetBundle并添加到实体
    commands.spawn_bundle(SpriteSheetBundle {
        texture_atlas: texture_atlas_handle,
        ..Default::default()
    });
}
