Issue description

If you want to place curve points on grid, it's currently impossible. If you have grid snap enabled and add a point, it adds a point off grid in an arbitrary location. If you try to move that point, it snap incrementally, so you can never get it on grid.

Steps to reproduce

• Make a 3D scene.
• Turn on "Use snap (Y)"
• Add a Path 3D.
• Ctrl+click or use the "add point" tool and click
• Note that the points are not on grid
• Try moving the points and note they do not snap to grid
