Sets the scale to a constant 1.0f.

Because Mac OS X *seems* to resolve DPI issues itself, we don't need to get the scale factor. The code has simply been commented out for now until this is verified to not suffer from "works on my machine" syndrome.

In my tests, a scale of 1.0f works on both a 15-inch retina MacBook Pro display as well as an attached Thunderbolt display.

**Please note:** If you run into issues with this on Mac, please file them at [my fork](https://github.com/dambrisco/CodeGlance/issues) as Vektah is unable to debug issues related to OS X.
