示例1: Init
/*-----------------------------------------------------------------------------------------------
Description:
Governs window creation, the initial OpenGL configuration (face culling, depth mask, even
though this is a 2D demo and that stuff won't be of concern), the creation of geometry, and
the creation of a texture.
Parameters:
argc (From main(...)) The number of char * items in argv. For glut's initialization.
argv (From main(...)) A collection of argument strings. For glut's initialization.
Returns:
False if something went wrong during initialization, otherwise true;
Exception: Safe
