Add the ability to crop a render
Currently if you want the object to fill the entire screen, you can choose "Fit to View" but this changes the perspective dramatically on a smaller object. Changing the aspect ratio doesn't quite cut it either. To get the perspective angle I need, I end up with quite a lot of 'dead' space surrounding the object that I have to go and crop in Photoshop later. Having the ability to set a canvas size or crop before saving would be really nice.
