Detailed Description

RHI renderer implementation for hardware-accelerated image display.

This file provides the RHIImageItemRenderer class which handles all GPU-side rendering operations for RHIImageItem. It operates on Qt's render thread and manages the complete graphics pipeline for displaying images.

Threading Model

The renderer follows Qt's threaded rendering architecture:

• GUI Thread: RHIImageItem lives here, receives setImage() calls
• Render Thread: RHIImageItemRenderer lives here, performs GPU operations
• Synchronization: synchronize() copies data between threads safely

Resource Ownership

All RHI resources (texture, sampler, buffers, pipeline) are owned via unique_ptr and automatically cleaned up in the destructor.
