a window handle
* Added `glfwGetWindowPos` for retrieving the position of a window
* Added `glfwDefaultWindowHints` for resetting all window hints to their
default values
* Added `glfwMakeContextCurrent` for making the context of the specified window

`GLES2/gl2.h` instead of `GL/gl.h`
* Added `GLFW_VISIBLE` window hint and parameter for controlling and polling
window visibility
* Added `GLFW_POSITION_X` and `GLFW_POSITION_Y` window hints and parameter for
controlling and polling window position
* Added `windows` simple multi-window test program
