Feature Request: Virtual Scrolling with Throttled Rendering

Hi Quasar Team,

Problem: Current QVirtualScroll uses debounce for scroll events (35ms / 120ms on iOS). This means new content only renders after scrolling stops , causing:

• Blank areas during fast scrolling

• Poor UX on mobile devices

• Content "popping in" abruptly
  Suggestion: Add throttle mode as an option:

• Render continuously during scrolling at fixed intervals

• Keep content visible while scrolling

• Configurable throttle timing
  Why:

• debounce : wait for scroll to stop → blank areas

• throttle : render while scrolling → smooth experience
  This would significantly improve the scrolling experience, especially on mobile.
