### Change Image Viewer to feel more natural to use.
([#686](<#686>) by @7w1,
@nushea, @Septicity)

- Fixed zoom gestures generally not working on mobile.
- Changed the % number in the top right to reflect the zoom of the
original image as opposed to the change from it fitting the container.
- Made the zoom pill allow entering custom values.
- Added a button that zooms you to the original size of the image, and a
button to return to the size that fills the container.
- Added a pixelated image scaling setting: choose Both, Chat, Image
viewer (default), or Neither for crisp nearest-neighbor rendering.
- Transitions are now disabled for manual panning to improve
responsiveness.
