Please don't auto-scroll the canvas, especially just on mouseover
I'm trying to align some components visually near the right edge of the canvas.
1. I scroll the canvas all the way to the right using the bottom scroll bar.
2. I move the mouse (without clicking) into the canvas.
3. The canvas scrolls left slightly, so I can no longer see the right edge of my work.
Please don't do that. Almost every time the canvas auto-scrolls, it makes things harder, rather than easier for the user.
