Add a way to hide the model preview

[AbigailBuccaneer]

I use Shdr as a lightweight shader IDE - none of the other IDEs or text editors I use have sensible syntax-highlighting or compile checking.

The live model preview is very cool, but I'm writing shaders that use many textures and attributes that simply aren't available in Shdr. Because of this, 50% of my screen space is wasted displaying an invisible monkey head.

(Even with this wasted screenspace, it's still by far the best tool I've found for what I'm doing. Thank you for this!)

Thank you for the feedback. I'll see what I can do :)
