Add High DPI GUI support

Add High DPI GUI support

Thanks so much for delivering your excellent product to us for FREE!

I have a 5K iMac, and the GUI on both the desktop and web versions looks low dpi and blurry. While it's more of an annoyance than an actual problem, it does reflect poorly on the brand/product.

Don't you have any modern High DPI monitors in your office? As a graphics technology company it would be more appealing to see you using the current generation standards. Having it blurry and low resolution kind of defeats the purpose.

Just an idea, I know it's a ton of work. So do as you can when you can!

Thanks so much!
