Improve the animation bezier editor 

- Allow snapping bezier handles to the timeline.
- Allow precise snapping when holding Shift for keyframes and handles.
  - Previously, it was only allowed for seeking the timeline.
  - This change also impacts the animation track editor,
    not just the bezier editor.
- Invert the Ctrl + mouse wheel behavior to match the zoom direction
  in the animation track editor.
- Increase the line spacing between the "Time:" and "Value:" texts
  to improve readability.
- Tweak box selection styling to match the animation track editor.
- Adjust line widths for hiDPI displays.
