Actually, for dev builds, we *do* need by default SystemJS modules

imgui-js needs to be imported as an ambient module from imgui_impl in order for typescript to not think that it's a separate module, and giving all globals (like bind) a suffix (bind$1)

The imgui renderer layer for the examples needs to take the devicePixelRatio into account when calculating pointer offset coordinates. Fixes #14
