Support for Scroll and Zoom Gestures in Slint

[worldyuan]

• Description

I would like to request support for implementing scroll and zoom gestures within a Slint interface. Currently, I am able to implement scrolling using Flickable, but zooming functionality through gestures (such as pinch-to-zoom) seems to be lacking.
Steps to Reproduce

scroll-event(e) add e.delta-distance event.report two finger distance.

• Expected Behavior

I expect to be able to use pinch gestures to zoom in and out on the content within the Flickable, dynamically resizing the elements while maintaining their layout.
Actual Behavior

Currently, there is no built-in support for zoom gestures in Slint, making it difficult to create a smooth user experience for zooming in and out on content.

• Code Snippet
  Example: Maps

• Platform: Linux、Windows、Android

• Programming Language: Rust
