[sable-actions]

Important

Merging this PR will create a new release.

Features

• Add per Space setting for when to show room icons in sidebar (#851 by @nushea)

Change Image Viewer to feel more natural to use. (#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.

Fixes

• Add support for stable mutual rooms endpoint, manually ported from this commit by ajbura upstream. (#852 by @7w1)
