OSX performance in 2.0.X

[ascloutier]

First off, let me say that I'm very happy to see continued development of Wings. I've been a long time user ever since Nendo disappeared.

I just installed 2.0.3 on my iMac running OSX 10.11.4, 32GB Ram, GeForce GTX 680MX and camera performance is pretty poor compared to 1.5.3. I loaded up a couple models I've been working on in 1.5.3, game stuff so it's pretty low poly (1700 faces), and the camera rotation is notably jumpy. Low framerate look to it. Same model with the same actions is silky smooth in 1.5.3.

Let me know if there's anything I can do to help with testing on Mac. I have a programming background too if it's helpful.

Thanks.
