Wishlist: 3D Histogram ortho camera / preset views

The 3D Histogram is really nice for evaluating RGB colors, but when you're trying to see velocity or disparity or normals or whatnot, it's often better to see from an orthogonal view so it's easier to compare near and far vectors. It's also common to want to focus on just 2 components, so "flattening" would be handy.

So I'd like an toggle for orthogonal/perspective camera, and it would be really nice to have either a menu or hotkey option to align to faces. So if I wanted to look at the XY plane, or ZY, or whatever, I could snap to that and know I have the correct location for the camera.
