M1Pro上Minilibx的工作速度很慢。

使用Metal框架替代Minilibx。

在M1 Pro上，Minilibx使用软件渲染，而不是硬件加速。这导致Minilibx在M1 Pro上运行缓慢。为了解决这个问题，您可以使用Metal框架，它是用C++和Objective-C编写的高效图形和计算框架，可利用苹果硬件加速来提高性能。

以下是一个示例程序，说明如何使用Metal框架替代Minilibx：

#import <MetalKit/MetalKit.h>

@interface MyViewController : NSViewController <MTKViewDelegate>

@property (nonatomic, strong) id<MTLDevice> device;
@property (nonatomic, strong) MTKView* mtkView;
@property (nonatomic, strong) id<MTLCommandQueue> commandQueue;
@property (nonatomic, strong) id<MTLRenderPipelineState> pipelineState;

@end

@implementation MyViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.device = MTLCreateSystemDefaultDevice();
    self.mtkView = [[MTKView alloc] initWithFrame:self.view.bounds device:self.device];
    self.mtkView.delegate = self;
    [self.view addSubview:self.mtkView];

    id<MTLLibrary> defaultLibrary = [self.device newDefaultLibrary];
    id<MTLFunction> vertexFunction = [defaultLibrary newFunctionWithName:@"vertexShader"];
    id<MTLFunction> fragmentFunction = [defaultLibrary newFunctionWithName:@"fragmentShader"];

    MTLRenderPipelineDescriptor* pipelineDescriptor = [[MTLRenderPipelineDescriptor alloc] init];
    pipelineDescriptor.label = @"MyRenderPipeline";
    pipelineDescriptor.vertexFunction = vertexFunction;
    pipelineDescriptor.fragmentFunction = fragmentFunction;
    pipelineDescriptor.colorAttachments[0].pixelFormat = self.mtkView.colorPixelFormat;

    NSError* error = nil;
    self.pipelineState = [self.device newRenderPipelineStateWithDescriptor:pipelineDescriptor error:&error];

    if (!self.pipelineState) {
        NSLog(@"Failed to create pipeline state, error %@", error);
    }

    self.commandQueue = [self.device newCommandQueue];
}

- (void)mtkView:(MTKView*)view drawableSizeWillChange:(CGSize)size {
}

- (void)drawInMTKView:(MTKView*)view {
    id<MTLCommandBuffer> commandBuffer = [self.commandQueue commandBuffer];

    MTLRenderPassDescriptor* renderPassDescriptor = [MTLRenderPassDescriptor renderPassDescriptor];
    renderPassDescriptor.colorAttachments[0].clearColor = MTLClearColorMake(0.0, 0.0, 0.0, 1.0);
    renderPassDescriptor.colorAttachments[0].loadAction = MTLLoadActionClear;
    renderPassDescriptor.colorAttachments[0].storeAction = MTLStoreActionStore;
    renderPassDescriptor.colorAttachments[0].texture = view.currentDrawable.texture;

    id<MTLRenderCommandEncoder> renderEncoder = [commandBuffer renderCommandEncoderWithDescriptor:renderPassDescriptor];
    [renderEncoder setRenderPipelineState:self.pipelineState];

    // do rendering here...

    [renderEncoder endEncoding];

    [commandBuffer presentDrawable:view.currentDrawable];
    [commandBuffer commit];
}

@end

在上面的代码中，我们使用MTLDevice、MTKView、MTLLibrary等Metal框架相关类来进行渲染。在drawInMTKView:方法中，我们编写了绘图代码，并将其
