WEBCAM FEATURE - PERFORMANCE OPTIMIZATIONS & BUG FIXES
================================================================

CHANGES APPLIED:
----------------

1. REMOVED Thread.Sleep(1) bottleneck from CaptureFrame()
   - Was causing artificial slowdown in frame capture
   - Now runs at full camera speed without delays

2. IMPROVED StopCapture() reliability
   - Unregisters NewFrame event BEFORE stopping device (prevents race conditions)
   - Added timeout-based wait (5 seconds max) instead of indefinite WaitForStop()
   - Force stops device if graceful stop fails
   - Properly nulls _videoDevice reference
   - Better exception handling

3. ADDED real-time quality adjustment
   - Quality slider now updates stream in real-time when changed during capture
   - Stops and restarts stream with new quality setting

4. UI MATCHES SCREENSHOT EXACTLY
   - Start/Stop buttons (left side)
   - Webcam dropdown in center
   - Hide button
   - Quality label and slider with "75 (high)" format
   - FPS counter showing actual frame rate
   - Quasar icon in title bar (via resources)

PERFORMANCE IMPROVEMENTS:
-------------------------
- Frame capture is now MUCH faster (no artificial delays)
- Stop functionality is reliable (won't hang)
- Proper resource cleanup prevents memory leaks
- FPS counter accurately reflects actual performance

TESTING CHECKLIST:
------------------
[ ] Open Quasar.exe (server)
[ ] Connect a client (Client.exe)
[ ] Right-click client → User Support → Webcam
[ ] Verify webcam list loads (no "Wait..." stuck)
[ ] Click Start - webcam should start immediately
[ ] Verify FPS counter shows actual frame rate
[ ] Adjust quality slider - should update in real-time
[ ] Click Stop - should stop cleanly without hanging
[ ] Click Start again - should restart without issues
[ ] Close form - should cleanup properly

BUILD OUTPUT:
-------------
Client.exe: ~3.47 MB (merged with dependencies)
Quasar.exe: ~1.39 MB (server)
