NUI does not respect Windows display scaling factor

[jellyton255]

What happened?

When rendering UI in game, NUI does not respect your windows scaling factor (set in your Display settings under "Scale & layout"), in general this is only affects users running on ultra high resolutions such as 3840x2160 with a scale set higher than 100%. The lack of proper scaling results in UI elements appearing uncomfortably small in game, whereas in a browser, they would appear as expected based on the chosen scale. Images below will illustrate this issue.

An interface in FiveM at 3840x2160 with 150% Windows display scaling

The same interface, in a browser at 3840x2160 with 150% Windows display scaling

The same interface, in a browser at 3840x2160 but with 100% Windows display scaling (equal to how it appears in game)

Scaling settings (for context)

Expected result

UI should appear "scaled" as it does when viewed in the browser.

Reproduction steps

1. Set "scale" in Windows display settings to a value greater than 100%.
2. View any in game NUI element in FiveM.
3. View that same NUI element in a browser.
4. Observe the difference in scaling.

Additional information

nui_useFixedSize attempts to solve this issue but does not suffice as a true solution. NUI elements appear blurry, and too large.

I've gone ahead and fixed this issue, however I'm going to do some additional testing before I make a PR. jellyton255@e6091ae
