vulakn技巧调用ssbo的值

如何从ssbo的buffer中调用值。

• 通过建立缓存，将memory和buffer进行绑定然后通过计算得出值.
• 测试直接的定点记录成功

		std::vector<Vertex> vertexBuffer =
		{
			{{1.0f, 1.0f}, {1.0f,1.0f}},
			{{1.0f,-1.0f}, {1.0f,0.0f}},
			{{-1.0f, 1.0f}, {0.0f,1.0f}},
			{{-1.0f, 1.0f}, {0.0f,1.0f}},
			{{1.0f,-1.0f}, {1.0f,0.0f}},
			{{-1.0f,-1.0f}, {0.0f,0.0f}}
		};
		.
		.
		.
		VK_CHECK_RESULT(vkBindBufferMemory(device, vertices.buffer, vertices.memory, 0));

		Vertex* test = (Vertex*)data; //成功我日！！
		test++;
		std::cout << "获取测试的值为：test->pos[1]=" << test->pos[1] << std::endl;
