Add native zoom

[horta-arch]

Overview

Requesting the implementation of a native, animated zoom feature directly within the window manager. The goal is to allow smooth zooming in and out on the desktop or individual windows without relying on external tools like wl-mirror, magnus, or third-party compositor extensions.

Motivation

A built-in zoom is essential not only for accessibility (helping visually impaired users) but also for presentations, recordings, and visual workflows. Currently, external solutions don’t integrate well with compositor animations and often cause visual artifacts or latency.

Desired Features

• Native GPU-accelerated zoom.
  Use the compositor’s rendering pipeline to apply scaling directly to the scene.
• Smooth animated transitions.
  Zoom in/out with fluid interpolation — ideally configurable (animation speed, easing curve, etc).
• Cursor and focus awareness.
  The zoom should center around the cursor or the area of interest dynamically.
• Configurable gestures and keybindings.
  Allow controls like Ctrl + Scroll or touchpad gestures to manage zoom levels.
• Multi-monitor support.
  Option to zoom only on the active display or specify which monitor to zoom into.

Benefits

• Fully integrated with the compositor (no tearing or flickering).
• Improves accessibility without external dependencies.
• Enhances the overall visual polish and user experience.
