JavaANAppSurfaceView.surfaceCreated 不移除所有纹理的话, 会有问题吗?

[EternalFire]

问题: JavaANAppSurfaceView.surfaceCreated 不移除所有纹理的话, 会有问题吗?

代码版本: 148d54077b1de819cf0958cc198b69ab97d67411

引擎代码: Java/Loon-Lite(PureJava)/LoonLiteCore, Java/Loon-Lite(PureJava)/LoonLiteJavaAN

例子项目: 使用这些目录里面的资源和代码Java/examples/assets, Java/examples/org, Java/Loon-Neo/src/assets, 创建了一个纯Java的Android Studio工程. 项目可以运行(拍拍手👏)!

但是, app 退到后台, 再返回前台, 图片不见了

但是, 文字还在, 按钮也在

打断点调试发现 JavaANAppSurfaceView.surfaceCreated 里面会清掉所有纹理.

public class JavaANAppSurfaceView ... {
	@Override
	public void surfaceCreated(SurfaceHolder surfaceHolder) {
		updatePpi();
		start();
		if (_game != null) {
//			LSystem.resetTextureRes(_game); // 注释这行
			if (_game.display() != null) {
				_game.display().GL().update();
			}
			LSystem.d("Created Renderer View");
		}
	}
}

注释以后, app 返回前台图片还在!!!

原例子代码的改动:

原例子有些代码在 LoonLiteCore 引擎里没有. 所以移除一些例子代码.

MultiScreenTest 里面移除了一些:

public class MultiScreenTest extends Screen {

    // ...

    @Override
	public void onLoad() {

        // ...

		if (page == 0) {
