代码说明：

每一个opengl都被连接到一个着色描述表上。着色描述表将所有的opengl调用命令连 // 接到device context(设备描述表)上,将opengl的着色描述表定义为hrc ,要让程序能 // 够绘制窗口的话，还需要创建一个设备描述表，windows的设备描述表被定义为 hdc, // dc将窗口连接到gdi(graphics device interface图形设备接口)。而rc-Each one opengl are connected to a shader description table. Rendering Context all the opengl call the command with// receiving device context (device descriptor table), on the opengl rendering Context is defined as the hrc, let the program can be// enough to draw a window, also need to create a device description tables, windows of the device description table is defined as hdc,// dc will be the window to connect to the gdi (graphics device interface graphics device interface).
