Client-side cursor rendering for remote desktop optimization

[Unkn0wnCreator]

Please consider adding client-side cursor rendering for “Optimize for remote desktop”.

Right now, if the cursor is only shown inside the video stream, mouse movement feels delayed. For remote desktop usage, it would be much better to send cursor position separately and render the cursor locally on the client.

Suggested implementation:

• separate cursor position updates
• separate cursor shape updates
• local client-side rendering
• hotspot/scaling support
• fallback when cursor is already embedded in the frame

RustDesk already implements this model and it greatly helps reduce perceived cursor latency.

This would significantly improve desktop responsiveness in Moonlight/Sunshine remote desktop scenarios.
