Having one way to retrieve the cursor position and another (more verbose) way to retrieve the monitor position is inconsistent. Having them both work the same way is the least surprising thing. The expected glfwGetMonitorSize function gets an added Physical in its name so users won't confuse it with glfwGetVideoMode.
