0026617: Visualization, Ray Tracing - adopt progressive rendering Path Tracing for rendering stereoscopic pair

Browse Source 
- Use two different FBOs for accumulating frames for left/right eye projection.
- Added equality checks to camera modification methods to avoid camera updates when performing identity operations.
