説明

I am writing an app that loads more than 400 PNGs into a scroll view.

But, it seems that VRAM is out of memory because too many images are being loaded.

I want to unload images outside the rendering range of the scroll view. Is there a way to know the display status of children elements in scroll view?

調査方針: Examine the existing widget implementations in the iced repository (e.g., the `widget` module) to understand how custom widgets are built. Look at the `Scrollable` widget to understand viewport detection. Investigate the image loading pipeline to see how images are currently managed. The issue comments may contain additional insights from maintainers and community members.
