To query the actual attributes * of the created window, framebuffer and context, see @ref * glfwGetWindowAttrib, @ref glfwGetWindowSize and @ref glfwGetFramebufferSize. * * To create a full screen window, you need to specify the monitor the window * will cover.

This will not affect its * OpenGL or OpenGL ES context. * * By default, newly created windows use the placement recommended by the * window system.
