方法名：glfwMakeContextCurrent

GLFW.glfwMakeContextCurrent介绍

[英]Makes the OpenGL or OpenGL ES context of the specified window current on the calling thread. A context must only be made current on a single thread at a time and each thread can have only a single current context at a time.

When moving a context between threads, you must make it non-current on the old thread before making it current on the new one.

By default, making a context non-current implicitly forces a pipeline flush. On machines that support GL_KHR_context_flush_control, you can control whether a context performs this flush by setting the #GLFW_CONTEXT_RELEASE_BEHAVIORwindow hint.

The specified window must have an OpenGL or OpenGL ES context. Specifying a window without a context will generate a #GLFW_NO_WINDOW_CONTEXT error.

This function may be called from any thread.
